It's never too late to start exercise

Unless you live to age 59.

"People who put off regular exercise until they hit the age of 50 can still benefit from physical activity but it appears to take 10 years for the effects to kick in, Swedish researchers said Friday.

A study of 2,205 Swedish men followed for more than 20 years from the age of 50 showed that exercise made no difference in premature death rates for at least a decade for those who waited until later in life to start physical activity."

Start as early as you can.

"'There is an effect but there is a bit of a delay,' Byberg said."

And start right.
