For the most part I'm hanging in there.
I'm 35, relatively new dad. A lot changes. I still play basketball 2x a week with people who are as mcuh as ~15 years younger than me, and I'm fine, but I've gone from being an asset on all of my teams to kinda being in the middle or not good. Like I'm the guy that the other team can put their bad defenders on now, which hurts sometimes. Still, maybe 2 or 3 games a season I can rattle off a really good game again. I've started shooting from distance, something I never did from 20-33, and now I'm not a bad 3 point shooter, in one of my leagues I probably average 30-40% from three because it's not as intense and I get a lot of open looks. In my other league where it's more intense, I only rarely shoot 3's, maybe one every couple games. But I'm trying to add that.
Heartburn was one of the worst things for me that came with age, but daily prilosec helps that.
Over the last 8 years or so I've gained about 20ish lbs, I used to nominally be around 200lbs (6'4"ish), and was in pretty good shape (never ever cut or buff, but not fat either). Now I'm usually around 220-225 most of the time.
I'm affected by injuries longer now.
I have horrible, horrible athletes foot that I have to treat every day or it's insufferable and literally like almost debilitating. THis sounds crazy, but it's the worst and nothing OTC works other than this random shit I found on AMazon that shouldn't work but it does.
WIth a baby, my sleep is fucked, but we're in a better place now than I was just amonth ago. My daughter didn't sleep through the night from age 1 year to about 14, 15 months... And I was always the one to get up and take care of her. I got serious with sleep training about a month ago and now she's sleeping like a dream for the most part. But, for a while, I Was getting almost no sleep... would rarely sleep more than an hour or two at a time, and it's still a problem for me. I'm naturally a light sleeper and probably wke up every hour or so at night, but I'm much more rested now and less affecte by it... for some time I was getting eye twitching throughout the day which was a sign (for myself) that I wasn't sleeping enough.
I had some health issues in my late 20s, developed hypothyroidism, have had some busted knees, ankles, and shoulders, and I have back pain from stupid shit. Injuries linger with me longer these days, but I'm holding it together for the most part.
