to go back to the joints I had when I was 40.
10 years down the line. I've got the start of arthritis in my left shoulder (popped the joint on a weight machine). Detached the bicep and reconfigured tendons in left arm. Don't try to bend your arm while carrying the 250lb concrete top of a bench one handed.
Tore my left achilles tendon last year - rock picking in mallorca without pre-stretching. Tore my left quadricep the year before.
Once the achilles had more or less healed, did something very nasty to my right knee and quadricep. Small tear in the quad but no clue what damage I did to the knee. It works, but definitely going to be a bastard as time passes. It's not quite the same shape as the left knee any more.
That was really painful.
Both knees are pretty much wearing out generally. Going uphill/stairs - no problem. Coming down, that's a sod.
I'm kinda paranoid about hospitals and doctors - so none of these injuries got diced and sliced. Way i figure it, it'll heal quicker without surgery.
Having a really high pain threshhold - isn't all it's cracked up to be.
I'm lining up to be a complete cripple by the time I hit 60.
On the positive side - my right arm and shoulder are solid. That's my throwing arm
Other than that, both being able to learn languages easily and playing a musical instrument are both things I'd love.
