My brother died of cancer at age 54. He was physically fit and did not smoke. What made him get cancer? Guess what, Summer, you might get cancer, too. The skinny lady down the street might get cancer. Fat people, skinny people - they can all die "prematurely."
I once saw a death cert. for a man who died of diabetes at age 76. His kidneys finally failed and he could not get a transplant. He had the disease since childhood. The cause of death was marked as "smoking." So now you think that "fat" should be the cause of death when someone dies of cancer? How are you going to blame yourself when you get sick, Summer?
