It seems like a pretty rudimentary test of conditioning, but Araujo found that it could predict life expectancy with alarming accuracy. He tested it on more than 2,000 of his patients aged 51 to 80, and found that people who scored less than 8 points on the test were twice as likely to die within the next six years. Those who scored three points or less were five times more likely to die within that same time period. Overall, each point achieved in the test accounted for a 21-percent decrease in mortality.
Araujo's study was only performed on patients older than 50, so the results won't mean the same thing for younger individuals taking the test. But regardless of your age, the test should provide a useful benchmark for your overall health. If you're younger than 50 and have trouble with the test, it ought to be a wake-up call. The good news is that the younger you are, the more time you have to get into better shape.
