I'm sure the scare you had makes a few life changes alot easier to stick to. I could probably use a heart attack myself, just to shake some sense into me. Probably wouldn't work though, I had a good scare a year ago that should have but didn't.
I really need to quit smoking and I need to get away from the work related chemicals that I've grown to take so for granted. I eat good, don't drink much, and get plenty of excersize, but at 52 I need to clean up my life a little bit more. We all probably do.
