Fast walking is key longevity, research says

(CNN, KYMA/KECY) - According to new research, fast walking could be the key to living longer.

The newly published study involved tens of thousands of participants.

They filled out a comprehensive questionnaire about their exercise habits, average time spent working out, walking speed, and health.

Roughly 16 years later, they completed another questionnaire.

Analysis of the data showed study participants who fast-walked for at least 15 minutes every day saw a nearly 20% reduction in premature death.

So how do you know if you are walking fast enough? According to the United Kingdom's National Health Service, you should be able to talk, but not sing.
