Spare the Air

Tomorrow, July 20, will be a spare the air day in the Bay Area. The ground-level ozone (smog) has been worse of late because of the high temperatures and no wind. Things you can do tomorrow to help:

On Spare the Air Days, we ask Bay Area residents to fight pollution by driving less, taking public transportation, trip-linking, walking, biking, choosing not to use gasoline-powered lawn and garden equipment, and avoiding polluting household products. People who are especially sensitive to pollution are advised to limit their time outdoors, particularly in the afternoon hours.

Travel is free all day on the following Bay Area transportation providers:
ACE
AC Transit
AirBART
Alameda Harbor Bay
Alameda Oakland Ferry
BART
Benicia Breeze
Caltrain
Cloverdale Transit
County Connection
Dumbarton Express
Emery Go Round
Fairfield/Suisun Transit
Golden Gate Ferry
Golden Gate Transit
Muni
Petaluma Transit
Rio Vista Delta Breeze
SamTrans
Santa Rosa CityBus
Sonoma County Transit
Tri Delta Transit
Union City Transit
Vacaville City Coach
VTA
The VINE

Trebuchet = Boy Glee

I gave my husband a trebuchet kit for his birthday. He spent all weekend assembling it, and we tested it Sunday morning. Very impressive results! Since husband is a private person, this is the photo I’m allowed to publish. Action shots are viewable by friends and family on Flickr. For friends and family who don’t use Flickr yet, it’s free and easy to create an account. Then add me as a contact, and I will add you, and you’ll be able to see the action!

H loads the trebuchet

If you want a trebuchet of your own, you can get one at ThinkGeek. Thanks to Tiffany and her husband for providing the idea.

California: Old Native American Word for “Inadequate Parking”

Given the movie we went to see tonight, we actually should have walked!

We went to see An Inconvenient Truth, which is a documentary by Al Gore on the global warming crisis. Parking was horrendous in the Santana Row shopping center. We wasted 25 minutes circling parking lots and the garage before finding a space. If we had walked the two miles from home, that would have taken 40 minutes and been better for us!

This movie contains some of the most important information about the risk posed to our planet and future. It’s based on solid scientific data, and while delivering it’s message is not sensational. I didn’t leave feeling despair. I left the theater motivated to take action to reduce my contributions to global warming. There’s also an excellent website with resources at this site. I’m going to learn more about CFL lightbulbs and purchase some. This is but one of the many small changes that can make a significant difference. Go see this movie!

Cool Ways to Re-use What You Think of As Junk

I learned today what a soda bottle looks like when it’s shipped to the company to be filled. It’s called a preform. When they fall on the manufacturing floor, they become unsanitary and cannot be used for consumables. They are recycled or shipped to a place such as RAFT, which uses them to make educational kits. They look like test tubes with screw tops and make excellent vials for storing small items (like beads) or using in basic science experiments (such as demonstrating how a seed germinates).

I also spent several hours using a paper cutter to cut the flaps off three-ring binders; these binders (some of them almost brand new) are discarded by the truckload by corporations. Rather than pile up in a landfill, RAFT has a creative use for them. The spine is put into recycling. The two flaps are then used to create a science kit called a “shake table.” Four small rubber balls are placed between the binder pieces and bound together by rubber bands on each side. Students are then asked to build a structure that sits on the platform that can withstand movement. The “shake table” when jiggled demonstrates earthquake tremors and is useful in teaching children about earth science.

I would love to see RAFT become a nationwide resource for educators. It started as one teacher’s idea to help other teachers get inexpensive supplies for hands-on teaching. Teachers typically spend $1,500 of their own money at retail stores each year to buy supplies for their students and classrooms; at RAFT they can get the same materials for $200.

Alas

My brain churns with thoughts, but time and energy are limited. Here’s a stream-of-consciousness example of what’s on my mind these days (in no particular order):

  • The history of the Black Panther movement and the 60s culture (I went to an exhibition at the Yerba Buena galleries today).
  • Community and social capital, i.e., how technology reduces this in-person but presents new opportunities for community via the Internet.
  • Musing whether these changes in community signify the doom of humanity and wondering if I’m a cynical idealist or just a realist or if there’s a difference.
  • Netsquared and their mission to support non-profits in adopting new web technologies to further their missions.
  • Life and it’s meaning; death and what comes after (if anything).
  • What truth is.
  • The first anniversary of my father-in-law’s death on April 2.
  • How I’m ready for rain to stop and warm spring to arrive.
  • Exercises that grab me by the lapels from a book I recently bought called The Practice of Poetry.
  • Cursing the fact that dust bunnies reproduce and wondering if there’s a simpler form of birth control than housecleaning.
  • Thinking about some essays my father wrote and sent me about his life experiences, and how I’m learning tidbits I’d yearned to know for years.
  • Percolating an idea for a project I’m to make to give to my Artella Spring Sprite recipient.
  • Saturday’s HOBA TeamWorks project at RAFT.
  • How pleased I am that my cholesterol levels are really low and that my doctor wrote a personal note, “Good!!” on the results that were mailed to me.
  • Wishing I’d read the book Jarhead before watching the movie Jarhead, which I’ve rented and will watch this weekend.
  • Creativity and personality and what type of mini-workshop I want to design regarding this.
  • What I want for dinner.

Optimize Your Brain

The brain is a three-pound supercomputer. It is the command and control center running your life. It is involved in absolutely everything you do. Your brain determines how you think, how you feel, how you act, and how well you get along with other people. Your brain even determines the kind of person you are. It determines how thoughtful you are; how polite or how rude you are. It determines how well you think on your feet, and it is involved with how well you do at work and with your family. Your brain also influences your emotional well being and how well you do with the opposite sex.

Your brain is more complicated than any computer we can imagine. Did you know that you have one hundred billion nerve cells in your brain, and every nerve cell has many connections to other nerve cells? In fact, your brain has more connections in it than there are stars in the universe! Optimizing your brain’s function is essential to being the best you can be, whether at work, in leisure, or in your relationships.

I’m Doing My Part This Weekend

None of us get enough naps. Naps are essential for mental health. Naps are productive — contrary to what we’ve been taught. Our culture promotes tension and crabbiness. Part of this is the severe lack of naps. Declare your home, or wherever you are, as a free nap zone.

–SARK

Yesterday I took a four-hour nap. Today I worked from 8:30-1:30, came home, and dove into bed. I awoke refreshed three hours later, ready to attend dinner with friends and engage in the delightful conversations for which I’m famous. *koff* Well, okay. At the very least I’m not crabby.

And I also managed to get Tuesday off as well, since I’ve racked up a bit of comp time, so I’ll get my three-day weekend starting tomorrow. Yum.

Self-Portrait Tuesday: All of Me Week 1

This month’s challege is to “embrace the mistakes, love the ugly bits.”

You are looking at my legs: chunky, sturdy, burdened with fat. They are scarred, dimpled with cellulite, and generally under-appreciated.

For many years I hated my body, especially my legs. When I was in 9th grade, I had a severe crush on a 12th grader. I was friends with his brother, an 11th grader, and confided this. This “friend’s” response was blunt: “My brother thinks you have a fat ass.” (And still I hung out with this guy!) Prior to that comment I had not felt consciously bad about my body. I had not dieted, nor had I fallen into obsession with weight. That comment literally changed everything. I spent the rest of my high school years feeling as though I had buttocks that were grotesquely large. I hated my curves. I wanted longer legs. And you know how much I weighed? Throughout high school I was 5 feet 2 inches and weighed at most 125 pounds. In my junior and senior year I dieted severely and began running and using laxitives. Sometimes I would binge on cookies and Snickers. My weight was as low as 118, and I continued to think that I was fat. I wanted to weigh 110. I never made it.

In my twenties my weight climbed, first to 130 until I was about 22, after which I reached 160 pounds. The summer I turned 25, I decided to try the rotation diet (not a bad diet if you can stick with it and use it properly). I also began running daily, up to three hours a day, because I was incapable of moderation. In a period of 12 weeks, I lost 25 pounds (my goal was to get to 125). I looked great. I felt great. I found a boyfriend. And then one day, I fainted in a mall. The doctor tested and found me anemic. His advice? “Eat more meat.” That was it. And my boyfriend, eager to take care of me, began feeding me huge weekend breakfasts. I didn’t own a car at this time and walked a lot, so the weight mostly stayed off for a couple of years.

When I moved to Austin, my weight crept up to 160 again and stayed there. This was okay by me. I worked out in a gym. I was flexible and strong. I wore size 14 jeans. I felt pretty good about myself. Then an elderly man who’d become a friend in a grandfatherly sort of way one day told me (after he’d had me as a guest for dinner), “You know, Kathryn, you’re pretty. If you lost 20 to 30 pounds, you might find a boyfriend.” If he’d punched my stomach, the effect would have felt the same. I was hurt and angry. I told him so. He apologized, but the wound remained. And his comment keyed into my fear that maybe it was true, that I would never meet a man who would want me whom I would also want — all because of my big fat ass.

At the end of my graduate program, I was talking with my advisor on the steps of a campus building. He was an older fellow, perhaps in his late 50s or early 60s. I had admired and liked him. For some reason, he felt compelled to suggest that I try whatever the fad diet that year was (I think it was Atkins Metabolife). He’d done it and he felt great! I was so pretty; I’d be even prettier if I were just a bit thinner… I was galled by his suggestion. It didn’t hurt as much because I was getting to a point of accepting myself more. I still found it insulting.

At another event I ran into a man I was acquainted with from a church I’d since left; he too was in his late 50s. His first words: “You look great. Have you lost weight? You look like it.” (I hadn’t lost weight.) I wanted to reply with, “Actually, no, I haven’t lost weight. I’m as fat as ever, thank you very much.” What was with these men?!

In 2000, my weight soared to over 200 pounds. This happened shortly after I met my husband. (He, by the way, loves me as I am. He wants me to be healthy and happy with my body, regardless of the number on the scale.) I dined out more often, ate larger portions, and drank more wine. I also stopped exercising. My husband is not very active, and being around him connected me with my inner couch potato. I’m not blaming him! I’m simply noting that I have a streak of laziness in me that proximity to another sedentary person had activated. It’s my responsibility to take care of my body. In the past couple of years I’ve made effort to work out more and lose weight; I’ve had limited success. Part of it may be aging — my metabolism is getting slower. Recently joining a gym has helped. I’ve enjoyed the variety of machines.

In 2003, the evening before Thanksgiving, I took a walk in my Austin neighborhood. I was thinking about my clients and my private practice when a pickup truck pulled up to the stop sign nearby, and a male voice yelled, “Only a husband could love those hips! What a fat ass!” Then they turned the corner, their hoots of laughter fading. I was the victim of a drive-by insult. And yes, that hurt.

We live in a fat-hating world. Women hate fat. They hate themselves. I went to the beach with some friends in 2000. I was at my heaviest, but I was okay with it. After all, I was with my girlfriends. Why not wear a swimsuit and have some fun? One friend who weighed only 116 pounds would not take off her shorts, because she was ashamed of her “fat legs,” even around three of her close women friends. How sad. When I commented that I weighed almost twice as much as she did, they all protested, saying, “You’re not fat!” O fercrissakes, quit lying to my face. Wait, you’re right: I’m not fat, I’m obese. Most men hate fat on a woman, too. Based on my experience, they’re more “honest” about it. Perhaps I should find that refreshing? Wouldn’t it be nice to live in a world where weight wasn’t at the forefront of most peoples’ minds?

I’m not happy with my body in its current state. I ache too much, my muscles are weaker, and my balance suffers. I used to be sturdy — not skinny, not fat, but solid. Coordinated. Consequential. I want my power back. Forget 125 pounds. Forget 145 pounds. If I were to get back to the weight I was at in 1999 — 160 — I would consider that a success. Until then, I’ll keep trying to love the “ugly bits.”

They Needed to Do a Study For This?

You might think parents worry most about whether their children are taking drugs, having sex or joining gangs. But a new survey of Bay Area parents reveals their biggest concern is that the day-to-day stress of modern life may be making their children overweight, depressed and less interested in school.

Homework and peer pressure are constants. Divorce, the area’s high cost of living and family feuds permeate many homes. Too many extracurricular activities and academic school testing keeps many kids hopping. And all around, many kids are feeling the need to grow up — and fast.

My 15 Minutes of Fame

Several months ago I was interviewed and photographed for an article in a national magazine. Yesterday I received my complimentary copy of the December issue. The article is by Sarah Mahoney, titled The Real-Life Stress Survival Guide, and published in Prevention.

Preparing for Disasters (Of Any Stripe)

Not much posting has occurred (or knitting for that matter) in the past couple of days, because I’ve been busy acquiring and organizing items for our family go-bags and home disaster kits. When we lived in central Texas, the threat was minimal. If a tornado were to hit, there would be no warning, so there seemed little point in having a kit. Besides, the damage would be localized, leaving much of the surrounding area unscathed. If my house were hit it would be a personal disaster, but not one shared by thousands of others demanding basic life support.

Now, however, we live in earthquake country. A big one could hit at any point; damage could be widespread. Of course there are other concerns too, though they feel vague: terrorism (biological perhaps) or an avian flu pandemic (not so vague). The aftermath of Katrina provided incentive to do something; I’d had the articles and lists ready for months.

I’ve been researching what is recommended and would like to share some information in case you decide to create your own. It’s a drudge chore, requires financial investment, and forces one to confront the possibility of Bad Things Happening. But now that we’ve done it (almost complete, just need to photocopy documents and purchase a few hardware items), I feel a bit of relief. I know exactly what to grab in order to survive and to take care of my cats, and I know where to lay my hands on it.

I’m not an alarmist, but the avian flu is a serious issue. So here are some links regarding this:

The CDC lists the following people as at-risk for the flu:

  • People 65 years and older;
  • People who live in nursing homes and other long-term care facilities that house those with long-term illnesses;
  • Adults and children 6 months and older with chronic heart or lung conditions, including asthma;
  • Adults and children 6 months and older who needed regular medical care or were in a hospital during the previous year because of a metabolic disease (like diabetes), chronic kidney disease, or weakened immune system (including immune system problems caused by medicines or by infection with human immunodeficiency virus [HIV/AIDS]);
  • Children 6 months to 18 years of age who are on long-term aspirin therapy. (Children given aspirin while they have influenza are at risk of Reye syndrome.);
  • Women who will be pregnant during the influenza season;
  • All children 6 to 23 months of age;
  • People with any condition that can compromise respiratory function or the handling of respiratory secretions (that is, a condition that makes it hard to breathe or swallow, such as brain injury or disease, spinal cord injuries, seizure disorders, or other nerve or muscle disorders.)
  • People 50 to 64 years of age. Because nearly one-third of people 50 to 64 years of age in the United States have one or more medical conditions that place them at increased risk for serious flu complications, vaccination is recommended for all persons aged 50-64 years.
  • People who can transmit flu to others at high risk for complications. Any person in close contact with someone in a high-risk group (see above) should get vaccinated. This includes all health-care workers, household contacts and out-of-home caregivers of children 0 to 23 months of age, and close contacts of people 65 years and older.

Yesterday while shopping at Costco for emergency supplies, I happened to notice a small line by the pharmacy. They were giving flu shots at a discount to members. Since I work with children and hope to become pregnant, I was considered a candidate. I also got a pneumonia vaccination, since I’d had it as a child and occasionally have some asthmatic breathing. A vaccination won’t protect you from all flu viruses, but some is better than none.

As for general disaster preparedness, I used the following:

One cannot prepare perfectly against disaster. That’s what disaster is: unforeseen devastation. It’s difficult to reconcile with the fact that we face the unknown all the time. I decided to prepare as best as I can — not to become pessimistic and morbid, nor to act like an ostrich and hide. It’s about finding a balance.

Lends New Meaning To “Turkey Breast”

The November issue of Discover (not online yet) has an article about bra research and design. In the past 15 years, women have generally increased one bra size due to obesity, implants, and estrogens from birth-control.

A pair of D-cup breasts weighs between 15 and 23 pounds — the equivalent of carrying around two small turkeys. The larger the breasts, the more they move and the greater the discomfort.

–Anne Casselman, Force=Mass x Acceleration, Discover

This can be a deterrent to exercise, and lack of activity can lead to increased buxomness. According to the article, the U.S. sold more than $5 billion worth of bras in 2001. Every woman should experience the comfort of good support, so I’m all for better design.

Blame the Victim

This excerpt features quotes of Mike Brown, the director of FEMA. Italicized words are my emphasis.

(CNN) — The director of the Federal Emergency Management Agency said Thursday those New Orleans residents who chose not to heed warnings to evacuate before Hurricane Katrina bear some responsibility for their fates.

Michael Brown also agreed with other public officials that the death toll in the city could reach into the thousands.

“Unfortunately, that’s going to be attributable a lot to people who did not heed the advance warnings,” Brown told CNN.

“I don’t make judgments about why people chose not to leave but, you know, there was a mandatory evacuation of New Orleans,” he said.

“And to find people still there is just heart-wrenching to me because, you know, the mayor did everything he could to get them out of there.

Victims Bear Some Responsibility, CNN

Um, gee. He doesn’t make judgments? Well, blaming the victims is exactly that. Apparently it doesn’t occur to him that the majority of those who didn’t evacuate were poor or infirm, or people caring for the infirm, or tourists. Many did not have the means — whether it was money, transportation, a destination, or all of these reasons. Even tourists. Imagine having flown in and not rented a car. Do you think you would have been able to arrange a flight out of the city last minute?

And no, the mayor did not do all that could be done to evacuate people. It’s not him personally, though; anyone in that position probably would have fallen short. Resources exist that weren’t utilized, because evacuation planners simply have never considered them. For instance, there were many buses (city, school) that could have been used to transport people out. However, where would they go? Disaster planning has got to include strategies to transport and care for displaced persons without money or with special medical needs. What we have learned from Katrina (I hope) is that this “every man for himself” method of evacuation is unacceptable. And now, policymakers and planners need to apply their brainpower so it doesn’t happen again.

Katrina Flood Aid: Each Dollar Brings 15 Meals To The Table

Second only to breathable air, people need food and water to remain alive. (They need clothes and shelter, of course, but air, food, and water are critical to basic survival.) America’s Second Harvest, the nation’s food-bank network, is calling for help. Donations to assist the victims of Hurricane Katrina can be made by clicking this link. It will provide instructions on how to give donations by phone, snail mail, or online. Ninety-eight percent of all donations go directly towards feeding hungry people rather than administration or fundraising.

Please help. Any amount will make a difference.
