If you need a good reason to exercise - here are five.

We should all be exercising every day...

Some people need a little more motivation than others to exercise. If you’re looking for a good reason, one of these should apply to you:

• Teenagers who exercise are more likely to graduate – and less likely to develop a brain tumor.

• Men who exercise vigorously are two thirds less likely to experience erectile dysfunction as those who don’t.

• Women who exercise tend to have fewer mood swings and better sex lives.

• Seniors who exercise three times a week are much less likely to develop dementia.

• People suffering from depression can lessen the symptoms by over 40% with aerobic exercise.

The bottom line is, people who exercise for an average of 15 minutes a day generally live longer and enjoy better quality of life than people who don’t.
