My dad is going through cancer treatment at the moment. He used to be so fit and active. The doctors recommend exercise and he would love to do more but he's feeling quite sick still from the steroids and other complications. I can't wait until Dad can go surfing and do yoga with me again. Short walks is all he can manage. He knows that exercise is important and would give anything to feel well enough to do more. It's such an important part of the recovery process.
