Great point!
A couple of weeks ago I went over the handlebars on my bicycle and broke my collarbone, needed 5 stitches on my forehead, got a little road rash on my hip, and an avulsion (?) fracture on one finger resulting in mallet finger. I'm 54 and have noticed that I'm healing much more slowly than I remember healing when I was a teenager.
Mostly, things are going smoothly and the only thing I'm really worried about is the mallet finger. I've been told to keep it in a splint for 8 weeks and if I accidentally bend it a little before then any healing will have to start over and I might end up needing surgery for it.
If anybody here has had mallet finger, I'd love to hear how it went for you.
Sorry to say I'm in almost an identical seat. I broke my thumb and have a gnarly but closed tuft fracture - after 4 weeks I saw a specialist who said there wasn't much healing or bone growth yet, and so decided to do a more aggressive splinting and lock down the whole thumb for another 4 weeks.
Oddly enough I had a similar injury 10 years prior on a different finger and that healed up in 6 weeks as if nothing ever happened to it.
Yep, something I'm realizing is a lot of guidelines/expectations around how long something will take to heal seem to be based on people in the 30-45 range. In your teens and twenties you might get injured and heal faster than expected and think "huh, must be my genes/technique/etc" when really it's probably just youth. Suuuuucks when you start to realize that superpower of yours is fading.
