i dont know thats an awful long time to hang around
say you wanna go to venice beach to work out with arnold, you had to wait 275 years
Let's say you keep your brain as it is now, but suddenly wake up tomorrow and it's 1700.
With all your knowledge you prepare yourself (eating correctly, start training as soon as you are able etc) to get in your best shape possible with the means possible , and then you stop aging as soon as you reach 22.
You would constantly be ripped/in good shape as you gain more and more knowledge over the decades.
Body of a 22 year old and the mind of an older man, gaining wisdom for each century.
Im sure you would have the patience to wait for a young Arnold to emerge 275 years from then.
