As a healthy/active person, I've noticed the unhealthy and overweight my entire life. However, recently I've begun to have an actual disdain for them. I don't know why, and I'm not certain I like myself for it. But, damnit, they just don't care for themselves. I see no difference between someone who eats themselves fat and a crack fiend ruining their life. Both are severe detriments to their health and longevity.
I also can't stand those who complain about being overweight and do nothing about it. My dear, fat friend, quit eating so much and you will lose weight. Hell, you don't even have to exercise!!
Yargh.
edit: None of this is directed to those who have the biological obesity pieces of DNA. That's not their fault and I would never claim that it is. My anger and disdain is directed to those who do not have biological obesity and are just lazy, eating too damned much.
As a side note, as I've aged, my metabolism has slowed down. I've made adjustments to my diet to compensate for this. Hardly what most other people seem to be doing...
