Muscle loss in aging tied to nerve loss: Ali Gorman reports during Action News at 5pm on March 14, 2018. (WPVI)

If your legs are getting weaker as you get older, you're not alone and British researchers believe it's due to a loss of nerves.

In tests, they found that young adults have 60 to 70 thousand nerves controlling leg movement, but that number drops nearly a third by age 75.

It drops even more in adults who aren't physically active.
