Catching joint issues early can make a big difference. For example:
1) dislocating the thumb joint at the base of the thumb is pretty common in mountain biking, need to pop it back in place right away, if you do not the old socket will start to fill in and then thumb will not go back.
2) shoulder joints are fairly open and so the shoulder can come partially out, then it can be injured easily, sports physician showed me how to check the range of motion of my shoulder, and if it was not good due to the shoulder being partially of the joint, how to get it back in position. Now when I feel any pain in my shoulder I check range of motion and also due a exercise where I fold my arm with fist to shoulder, and then rotate elbow towards head in a circle to get shoulder back into the joint.
Watched the Malin method introduction video that Loonie posted the link for, Malin points out how leaning over to look at phone and tablet is bad for shoulder joints. I just got a Levo G2 deluxe tablet stand, no more hunched shoulders and crooked neck for me!, they had a refurbished one on sale for $150, so I got it, remarkable how much better my posture has gotten, use at the counter and also when in my recliner laying on my back.
