> More realistically, a man who is 35 years old has a life expectancy of another 43 years, so not quite there yet.

It's crazy how much this can vary. I'm 34, but I'm female and from a family where multiple people have lived to be over 110. I've always estimated my 'mid life'/halfway mark to be about 45.

Sure but the effectiveness of upcoming years seems much higher. Where I used to toil for 10 hours to do something, I can do the same thing now in 1 hour.

Resources are higher too. For lots of things that used to take time, I can just pay someone.

And lets not forget I spent the first 10 to 15 years being basically useless.
