One bite will render you fit and well from any injury or disease.
A second bite will roll back the years to your physical peak.
A third bite will give you eternal life.
It's a big apple, you get 6 bites.
What do you do?
Assuming this just changes me physically (that is, I won't erase the last 14 years of my life), I'd take two bites, putting me back to my mid-20s peak, then pitch the apple. Eternal life (outside of some transdimensional evolution) never had any allure to me.
