I have a friend, Cindy, I've known since grammar school, she's no more than 5' 5"", she was a cheerleader in high school. I gave you that background to put in perspective meeting her 30+ years later, and my reaction to seeing her, over 400 lbs, conservatively, I'm sure my jaw dropped visibly, I couldn't help it. She wanted a ride on the bike, I never considered her weight, she pulled me right over trying to get on. I made her get on with the kickstand down, we went to lunch with some friends. Time to get on again, I thought, hell, I can do this. Absolutely no way, I was braced with all my strength and 100% ready. Nope, Charles Atlas couldn't have held that bike up, pulled it over again, she actually grabbed the front handlebars trying to get her leg over, never had anyone do that before.
She had the stomach surgery, lost 160 lbs, then a second surgery to remove lord knows how much extra skin, and well, it was hard to notice, she was still obese, so I can't really imagine what her peak weight was, sad really, I can't see how she can live very long that big.
