We still live in an age where we expect instant cures- a pill or a shot NOW to fix our ailments. Yet, we overeat and live flaccid lives- which make us more susceptible to diseases. Recently, the government has suggested that we need 150 minutes of exercise a week and to give up sugary drinks. Not only does that work to reduce our girth- but data are now showing that exercise is critical to preclude- and improve- the treatment and rehabilitation of devastating diseases. We have known for years that exercise is a critical regimen in the treatment of cardiac patients. Many asthmatics have proven that swimming precludes attacks and alleviates symptoms. We can now expand the use of exercise to cancer, autoimmune diseases, Parkinson’s disease, and, even, dialysis patients.
