Stick to selling cars, Bostonian. How can you presume to judge the background of every single person who wants to get that surgery done? Here's an anecdote that may enlighten you, if it somehow gets through: I work with a guy who used to carry just under 3 bills when he was a football player in college. 10 years later, he was near 400 and big as a damn house. Not a good situation at all, his knees hurt, he couldn't play with his kid, all that. The thing of it is, he tried every diet plan imaginable short of starving himself. The best he could do was to lose 20 pounds, not much of a dent when you weigh 400, and he was miserable doing that because even at that weight, HE WAS ALWAYS HUNGRY. Without a doubt, he hit the bad luck lottery when it comes to genetics--the guy is hardwired to put on pounds.
So he got the surgery. It nearly killed him. 6 blood transfusions later, the worst was over and his stomach was a fraction of its former size. He can't eat more than a really small amount now without feeling uncomfortably full, whereas before he never felt full, even after polishing off a large steak and cheese. In fact, he eats so little nowadays we all wonder how he doesn't faint from lack of blood sugar. Anyway, he's lost close to 200 pounds in a little less than a year. The before and after pictures would make your jaw drop.
His experience with the surgery, its complications, and its effects are quite similar in fact to those of Charlie Weis, the Patriots assistant coach who got some press this year when he nearly died in post-op. Like the guy I know, Weis tried every diet imaginable with only modest weight loss to show for it. Even a restricted, 1500 calorie a day diet (think about how tough that is for a minute) didn't make a dent.
Guys like Weis and the dude I work with may not represent the majority of people requesting the bypass surgery, but there are people like them out there. Idiots like you would instantly judge them as being lazy, undisciplined slobs. What's interesting is that if you asked the guy I know if he would recommend the surgery to someone else with similar weight problems, he doesn't say "oh yes absolutely." Far from it in fact. He was scared shitless when they kept pumping blood into him and it kept leaking out his stomach staples. His wife had some doubts about how safe it was beforehand, and he reassured her that it was no big deal. He says that knowing what he knows now he wouldn't have been so quick to agree to being stapled, but he can't argue with the results.
Moral of the story: don't lump everyone into your preconceived categories based solely on what you see. Get to know the person before you judge them.
