Just one more reason to take the stairs…
A study published in the journal Neurobiology of Aging (February 2016) by Jason Steffener and colleagues showed that the more flights of stairs a person climbs, and the more education a person has, the “younger” their brain physically appears.
The authors used MRI to examine the brains of 331 healthy adults who ranged in age from 19 to 79. They looked at the relationship between gray matter volume, which tends to decrease with age, and the amount of exercise and education their participants reported. Steffener and colleagues found an approximately 1 year decrease in brain age for each year of education and 2 flights of stairs climbed.
