When it comes to exercise, every bit really does count.
Its benefits show up whether you exercise a lot--or a very little.
Studying 4,280 over-40's, researchers found something interesting.
The more subjects exercised, the less likely they were to be dead at the end of the study.
But even subjects who only exercised five minutes a day extended their lives!
So take the stairs and run for the bus, and don't worry about skipping the gym!
