Amen to Zebo and Booger
I assume the whole point to life is to just LIVE IT, and not treat it like this priceless baseball card you've got to keep in mint condition by putting in two layers of plastic and never exposing to the sun. Yea, it may last a lot longer than others, but is length the only measure of a healthy life?? I cherish my quality of life so much more than my length. If you just live, and don't abuse yourself, the duration of your life will take care of itself.
Like Zebo said, and what so many others have already discovered is essential to a quality life: "Moderation is the key." The same principle was emphasized during the prime of the Classic Greek culture, but they just referred to it as balance. Life as we kow it, functions according to balance.
And since when the hell has exposure to the sun become dangerous???
