Two ways to answer this, one is that I dont want to live long enough to die of old age. However after seeing my dad die from cancer at 51, just 5 years ago, and now my mom is 55 and will probably be alone for the rest of her life I definitely dont want to check out early on my wife. I recently went through an illness and thought I was a gonner for sure. Docs told me I should have been dead, I wasnt scared for myself, but I kept thinking about my two girls, 11 and 8, and my 2 yr old son. I cant think of anything worse than leaving them without a dad.
