AS IF IT WAS really necessary to perform many experiments to prove this...
People who stay single, or become single again by divorce, may be somewhat more physically fit than those in wedded bliss, a new study suggests.
The research, which followed nearly 8,900 adults over several years, found that both men and women who got married during that time tended to experience a dip in cardiovascular fitness, as measured by treadmill tests.
In contrast, men who got divorced during the study saw a modest increase in their fitness levels.
The findings, reported in the American Journal of Epidemiology, do not prove that a change in marital status directly causes the change in fitness -- for better or worse.
Still, researchers say the results support the notion that once people are married and, presumably, off the dating market, they tend to let themselves go a bit. But if they remain single or get divorced, they have more incentive to get in shape.
