Lets say in 2050, they roll out a health care robot. It costs $50 and runs on solar. It can diagnose and cure you of all kinds of things. For the things it cannot cure, it will just grow you a new body (18 years old) and transfer your consciousness into it (in a perfect and painless procedure). Itll even have an emergency backup version of you stored in case of sudden death in the cloud.
Would you still eat healthy? Or just pig out until you get fat and jump into a new body? How about risk taking? Would you go parachute jumping? Dive off a cliff into water? Lots of drugs youd never touch otherwise? What else?
