KNOW AND CONTROL CHOLESTEROL LEVELS: Almost 40 per cent of Canadian adults have high blood cholesterol, which can lead to the…
Past experiments have shown persuasively that exercise spurs the birth of new mitochondria in muscle cells and improves the vigor of the existing organelles. This upsurge in mitochondria, in turn, has been linked not only to improvements in exercise endurance but to increased longevity in animals and reduced risk for…
The glib words of years past from our politicians are hollow nightmares indeed when we are confronted with the staggering realities of what has to be done. But the key is there--technology, using it-and we hardly do now. The future may be unpredictable, but we can make a few well-aimed guesses about what life will be…

An "android" fat distribution-—fat on the belly, thin hips—is associated with the symptoms of male disabilities such as…
