I'm on vacation now, thank goodness, so I celebrated by sitting around all day and working on a new look for my design site (it's not quite finished, though, so you can't see it yet). It was just like the old days: hours and hours straight of sitting in front of the computer. I should do it more often. I did notice, however, that the combination of sitting still and concentrating intently did something peculiar to my appetite--to wit, killed it off entire. And it's not just that I was working hard I forgot to eat, though that was a factor; when I finally did get up to get myself some nourishment, my eating was more in the nature of a necessary preventative measure than a reaction to actual hunger. Compare that to a typical day at the kindergarten, when I'm starving by ten oclock (thank goodness for snack time) and then manage to eat a substantial lunch at 12:30, on top of who knows how much food for snack.
So, in other words: despite what The Simpsons may say about 'constant sitting and snacking,' I could never get fat on a programming job. For more reasons than one, now that I think about it.
