Our body is truly our greatest treasure. Even if you are the richest person in the world financially, if you do not have a healthy body, your wealth does not matter.
When something goes wrong in the body, other organs and cells are also affected. Someone with leg problems cannot walk, they will probably gain weight. They will be immobile, their blood flow will decrease. Blood pressure and similar problems will occur. Again, someone who moves less will tend to get depressed.
"Probably" ;D
The reduction in blood flow in the legs can lead to other problems later, so it is best I try and get it sorted out soon. I am not getting younger!
