12: If you were able to live to the age of 90 and retain either the body or the mind of a 30 year-old for the last 60 years of your life, which would you want?

Considering that my 30 year-old body was literally one of my most unhealthy years, I guess it would be a 30 year-old mind. However, I would prefer to be 90 however it would naturally turn out. I want a 90 year-old body and mind at 90. I don’t need to be younger than I already am. I don’t believe we need to cheat the effects of aging, but enjoy what we have as we have it.
