What are the long term effects of physical activity on the muscles?

If you have an appropriate amount of muscular excercise and eat an appropriate amount of protein you will almost always gain muscle. If not, you will almost always lose muscle.

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.
