Okay, this is probably not a question that a lot of guys here might want to answer, but it's actually the only place where I feel I would get a reliable answer. I'm doing some investment calculations, retirement planning etc, and I'm thinking "okay, this is all great, but in which years can I actually enjoy my youth? In which years can I actually enjoy a healthy and functionally correct body? In which years is my body basically useless and it doesn't really matter anymore?"
Is there any rule of thumb, or does it all depend on how well you take care of your health? Are there 70 year old men who don't need viagra to get a raging boner and plow a girl? 80 year old men? I can't really imagine a 90 year old....
All this is part of a bigger, grander question of how to live my life. Work hard, preserve my health, invest ALL my discretionary income and retire early (40 years old) and then party until I die? Or work mostly hard but also slack off to go after girls and have fun with my income now? These aren't questions that you guys can really answer for me, but the earlier questions you certainly can.


I'm under 40 so I can't answer your question, but I can tell you what I've decided when contemplating similar goals.
I've decided to play while saving for retirement. I know retirement will be pushed back a few years but I got to enjoy my youth. The last thing I'd want is to delay fun to save like crazy to retire and then get hit by a bus.
Plus the girls at the club I'm sure behave a little differently to guys that are closer to their age then they guy is to 50+. Enjoy that while it's still possible is my plan.
