Happy early Birthday to you!
I've got 10 years on you, and definitely relate to your list. As the years wander by, the main difference I notice isn't problems with the doing of things, but how long it takes before I no longer feel sore. 20 miles of hiking? No problem! Just don't ask me to do anything else for 2-3 days!
Thank you! At 50-something I would totally agree. There's not much I can't do but everything takes more forethought and recovery time. Lol.
