If you were able to live to the age of 90 and retain either the mind or body of a 30-year-old for the last 60 years of your life, which would you want ?
That would be one for Stephen Hawking. If he could get his body back, and have his 30 yr old mind, he would be doing pretty well. Speaking for me, I am not ashamed of my mind at 30, so I guess I would take the body. Then I could rope out of a helicopter again.
