Aging cartilage is a big problem in the general population, but it can be especially vexing for the master athlete who has no time or inclination to be slowed down by the pain or swelling that often accompanies cartilage that is "running out." Keeping cartilage healthy is a real balancing act for mature athletes. Inactivity and disuse atrophy can decrease the health of cartilage, causing softening, fissuring, and potential mechanical compromise.
On the other hand, high-energy, high-impact activity on degenerated cartilage can cause increased wear. If you are a jogger or basketball player over 40, you must take this into consideration by listening to your body and the pain messages it sends. Such messages tell you that you are tired, that there is a problem or damage, or that the soft tissue of your joint is inflamed.
When you feel these signals, be smart and stop or moderate what you are doing. You will make no gains by ignoring the pain and continuing to abuse your cartilage.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
