I read that my age group (I'm 42, almost 43. I think. I honestly quit counting at 27 and now I just guess mostly) is the cutoff age for DIYers. People older than me still often tackle their own projects like y'all are talking about here. People younger than me didn't learn any carpentry, basic appliance repair, auto-repair, etc. They almost exclusively hire stuff done. Somewhere along the line dads quit teaching their kids what they knew about that stuff and kids quit being interested.
My grandpa (on my mothers side) was incredibly handy. My father's father died young of a heart attack, I never met him. My dad was taught a lot by my mother's father, and then he just had a DIY book he consulted. He built two decks, a treehouse, did all of our landscaping, finished our basement, including electrical. Just with that damn book. I hung a new light fixture, and felt like I needed to brag on social media about it.
But I do minor home stuff, and my FIL is the exact opposite, asking why I don't just pay someone to do things like stain the deck. I mentioned once that I was painting the bedrooms, and he asked to come help. Lasted 5 minutes, and then tapped out when I started taping. He's about to turn 70, but this was like 7 years ago, and it wasn't due to physical limitations, I think it was exclusively due to not realizing the minimal amount of work that went into painting a room.
I won't do electrical, granted the prior electrical on the light fixture I hung needed some reworking, or plumbing, with a caveat that once I did some plumbing work in our bathtub, because the only leak was going directly into the tub, so I felt confident that (a) it wasn't getting worse while I was figuring it out and (b) if I screwed it up worse, the water bill would just keep going up, it wouldn't cause additional damage
