I'm 55. My dad died the day after his 74th birthday. He had smoked heavily since age 11 or 12, drank heavily probably just about as long, cooked everything in lard and ate mayonnaise out of the jar. He survived a big heart attack in his early 50's and bypass surgery later in life but it was cancer that eventually got him. I don't smoke or drink but I am over weight, I do stay pretty active. I feel like I deserve at least as long as he got (it's not easy typing with these crossed fingers).
