The World Heart Federation warned in September, 2003 that failure to exercise is as bad for one's health as smoking a pack of cigarettes every day. Physical inactivity doubles the chances of developing heart disease and increases the risk of diabetes and high blood pressure.
Doctors estimate that between 65% and 85% of the world's population fail to take enough exercise. Two out of three children around the globe take too little exercise to improve their health. This is particularly true in Westernized nations where higher standards of living, modern conveniences and urban environments make exercise unnecessary and less enjoyable.
