Welcome to 40's, Sir-Kill!
Speaking of what we have now and what we had in the past, let me tell you something (albeit something quite surreal and farfetched):
I'm ready to give out my house, my job, all my money (virtually everything
except my knowledge and experience) just to be 20 years younger. Nothing can be compared with youth and health. I'm not even talking about time-travel to 20 years ago, just being 20 years younger in the present time and as healthy as I was 20 years ago.
Hey, if it could be a time-travel, I would even agree to give up
more (for example, paying 75% of all my income in the rest of my life and keep only 25% of what I earn
). If you know any supernatural being who makes such deals, send him to me.
