Every now and again, someone points out the enormous benefits to healthy life span that can be attained by universally preventing the most common fatal illnesses of aging. Here is one from the New Scientist: researchers estimate one or two decades of additional healthy life could be gained by having everyone over 55 take a daily pill containing the most effective drugs to prevent stroke and heart attack. The prevelance of these sorts of violent heart problems are quite possibly a consequence of poor diet, however. A person on a calorie restriction diet might gain the benefits offered by the drugs in any case. Still, food for thought.
