The good news is that we seem to be living longer. The not so good news is that we're all less healthy! Certainly if we compare the post war baby boomers with the generation which preceded them. Life expectancy might be rising, especially as new medical advances are made, but the question is, are we doing enough to keep up our end of the bargain and take responsibility for our own health and fitness too? If not, then an aging population and increasing healthcare costs could be debilitating to a country's economy, and to individuals as well.
