An Example of How Exercise May Not Be Enough

Many people believe that exercising a lot will keep them healthy, and that the exercising will make up for any unhealthy foods they eat. However, that doesn't seem to be the case. For example, former President George W. Bush is recovering from heart surgery. This is surprising, because he exercises regularly. Yet, all the exercising he did wasn't enough to prevent the blockage in his artery. What's scary is that there might not be any symptoms other than the heart attach itself.
