I was walking to work today, past an advertisement for some sort of hair and beauty management place (I've never paid much attention to what you call them, just that other people, especially the ones without Y chromosomes, have things done to them there.. often resulting in their hair looking different). Anyway, they had a bit of suggestive advertising that caused me to start wondering if there's any sane rationalization left for showing only male nipples in public. It was very cleverly laid out - a very thin female model with a towel wrapped around her "upper midsection" with a male model behind her placed such that my train of thought was something on the order of "picture of girl. nipple. HUH? oh." So it got my attention, but unfortunately for the advertiser my idea of hair care is regular degreasing with occasional mowing when it gets in my eyes.
Those of you who know me might be slightly surprised by the first clause of the previous paragraph; Karl walking? His car must have broken down. Actually, my weight recently spiked enough to scare me, and I've decided to become assiduous about walking to work, and also try to eat more slowly. It's a sad comment on my personality that it took me being personally disturbed by my health to start doing something about it, despite many people who cared about me telling me that I should do something for many years prior. To you, I apologize - and my thanks for putting up with me as much as you have.
Eating slower has also been an interesting experience. My general m.o. has been to spear a piece of food on my fork, or otherwise hold up what I'm about to eat, and look at it and try to think about it, and be at least fleetingly cognizant of every bite I take. It cut my normal lunch yesterday in half, and I didn't end up any more hungry than I usually do. (My flip description is that I meditate on how each bite feels about being eaten, but given my excellent track record in only eating things that are dead, I think the answer is "Not much".)
So anyway, I've been walking to work, an activity that I've rejected in the past as inefficient, and contrary to my impatient, "instant gratification isn't fast enough" nature. I've actually found that it gives me time to think of things that I'd otherwise think about behind my desk, staring into space. Furthermore, I've also observed that "real" bloggers seem to get a lot of mileage out of quitting smoking or the like. I don't think I'm going to quit eating, but I can at least cut down a little.

Eating more slowly helps with the portions a lot. My method for this has been to count what I eat (I guess Weight Watchers inspired this). It seems to be helping.
It slows me down AND I know how much I've eaten. It's pretty neat.
As for thinking time: yes. Back when I parked at Alewife, it got me (1) some walking [a couple of blocks inside alewife itself, another couple at the other end] (2) time not just to think, but to mentally regear from fast-twitch-driving to a more thinking-and-designing conducive pace (3) pictures! (a lot of the cool pictures in burnbeforereading are from that commute.)
The disadvantages (non-determinism, alewife *does* fill; insane lines at departure times, especially when they got stupid and went to $4.50 instead of $5 for the fee; random delays in actually getting to the office from there) outweighed all that in the end, though.
