They don't live as long as people with normal weight.
The Soda Pop is so loaded with Sugar that they become badly addicted, and can't stop.
I know a woman who drinks 12 cases (of 6 bottles) of soda pop a day, and she demands the real sugar. No diet pop for her!
She tips the scales at 400+ lbs and could care less about health problems. She is on welfare & lives in her mother's house in the attic. She scoots up the attic stairs on her butt, because she has great trouble walking. Been this way for decades.
