Trivia Question: How Long Will You Live?

What key health measure is the best predictor of how long you will live?

1. Blood pressure
2. Blood sugar levels
3. Cholesterol levels
4. Level of fitness
5. Waist measurement

The answer is number four—level of fitness. You can reduce your risk of death (even if you haven't lost weight) if you maintain or improve your level of fitness.

"This is good news for people who are physically active but can't seem to lose weight," said Duck-chul Lee, PhD, the study's lead researcher.
