Exercise: Better Late Than Never

The Scientific American reports on research conduced by Dietrich Rothenbacher, an epidemiologist at the University of Heidelberg. Rothenbacker and his research grouup surveyed 312 patients between the ages of
40 and 68 who suffered from coronary heart disease and 479 volunteers
matching the patients in age and sex. The scientists asked them to

the age of 40 enjoyed a 55 percent less chance of cardiovascular
trouble. Those who went from being inactive to very active saw the
greatest benefits.
