Yeah. I used to run pretty fast. I mean, not olympic gold medalist fast but faster than 90% of anyone else I knew (Fairly short distances). I don't even know if I can run at all anymore but it probably wouldn't end well if I tried. :lol
Excessively drink the night before and still function with a hangover the next day. Now a days if I drink more than 3 drinks, I'm in bed all day the next day. Also, junk food agreed with me a little bit better back then
Back when I joined SAS I used to stay awake for 30 or 40 hours at a time for fun, now trying to make it 20 hours is an ordeal. But that's about it. For the most part I feel physically better at 40 than I did at 20, thanks to the magic of having been a really lazy and underweight young person.
I could get by on a lot less sleep. In my teens I could sleep four hours or even stay up all night and still function. Now if I only get six hours or less one night I feel like death the whole next day. Posted via Mobile Device
^ I can still stay up for as many hours as I used to (sometimes) but I usually don't try to. And I wasn't really trying to back then. I had chronic insomnia and it did me no good to try to sleep if my body wasn't ready for it. I'd lay down and just lay there wide awake for hours on end. So I would pretty much just lay down and wait an hour or so and if sleep didn't happen, I'd get up and do whatever I felt like doing because I knew I wasn't going to be able to sleep anyway and I might as well enjoy the extra time.
Doing whatever I want without more obsessing at the potential risks and how things can go wrong of doing so. I was so much happier back then for that reason. But when I was younger, I probably had much more room and leeway for mistakes, which I don't now.
Also not being able to do what they're doing below, without back pain flaring up within 5-10 minutes. Just looking at the farthest girl, my upper back starts kind of flaring up.
I probably wouldn't be able to walk or run 1/4 of the distances I can today without feeling like crap and complain. I am in better physical shape I am now than I was young. Although general healthwise, it's probably the opposite.
Lots of things physically. I was helping my wife paint some posts out the front of her house the other day I got quite dizzy just looking up. Also things like mowing the lawn etc or physical work - I could do that easily when I was a kid.
Probably couldn't study the way I used to - my mind is too much of a mess nowadays and I find it hard to focus. Work would also be very difficult - my situation seems to change from day to day quite often so it would be hard to commit to anything.
Braver in driving or going very long distances, like a few hours away from home. I remember I use to drive 2 hours away to try a food spot back or try a hiking spot back in the days. No way I'm willing to do that now.
Befriend and get comfortable with new people easier and quicker. Now I'm gradually going the opposite as I get older. Typically for most people, it gets easier as they get older, they're more mature and less constraint socially as they experience socializing and the real world more. Opposite for me.
Lastly, just having friendships and relationships I had back then, that I no longer have now. Because they ended. Due to being bad on my part at maintaining them, or bad also on my part in remaining interesting and rewarding for others to want to maintain one with me.
