An opportunity presents itself, you are offered the choice to stop yourself from aging, and if your old you will revert back to a youthful adult. It doesn't include immortality, simply a chance to potentially live perpetually, lets say it also includes the inability to get sick in anyway. You would only have to worry about death by unnatural causes. Also say that it is offered to everyone everywhere.

What would you choose to do, and why?

Considering the effects of entropy, if I could return to my former self at 17 years old physically I would do it in a minute even if it meant "selling my soul to the devil" - of course, I'd like to keep the knowledge I've retained over the last forty years or so but still - to be 17 again - you betcha!!!

No. It was bad enough once, I'd rather age gracefully and rest in peace.

Another 50-60 years ahead of me before retirement... dear god I'd kill myself lol
