I thnk 10 100 year lives for a few reasons:
-People already look horrible at age 100, one can only imagine age 1000.
-I wouldn't want to be the same guy for a 1000 years if I option for 10 different lives.
I could probably be a man in one life and a woman in another, how interesting is that o.O .
Would you rather be a professional musician or athlete?
