What can cause stress on the knee and hip joints?

When a leg bone is rotated out, the feet will usually have to follow by pointing slightly outward too. If instead the feet point straight ahead (which we are all taught to do when walking and running), then adverse stresses will be placed on the knee or hip joints. This is because we are trying to override a normal biomechanical condition with our socialized expectations of having feet that nicely face forward.

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.
