Life Insurance is too Definite

I keep getting these things in the mail for Globe Life Insurance and from other companies. For some reason, I always save them because I don't feel right about throwing them away. But I can't bring myself to open them yet, either. I'm only 31 years old and I know I should start thinking about Life Insurance for the well-being of my wife. With my weight and genetic disposition, I need to start thinking about this kind of thing pretty soon, too. But when I look at the envelopes, they seem more like Death insurance instead of Life insurance. It's too certain. It's too definite. We're all going to die and I think about dying alot. But when you actually buy the insurance, it's almost like admitting that you could die anyday. And while that's true, who wants to think that today could be the very last day of their lives?
