The prime years

Today I'm 37. Am I in my prime? There has been my debate about what the prime years are. Is it the teen years? The 20's? The golden years. Actually, it's pretty simple, in my expected life expectancy, there's 21 prime years, and I'm in one of them. It started at 2, then 3, then 5, then 7. I never really understood until now, but now that I do...gosh darnit, I'm going to embrace it. Odd as it may be (certainly not even), I've only got about 9 of these left.
