Want a younger brain? Stay in school — and take the stairs

I take the stairs as often as possible even though doing so is incredibly slow because I have to think out the complete process. See here for what your stair climbing should look like. What protocol is your doctor following to have you get a younger brain?

The researchers found that brain age decreases by 0.95 years for each year of education, and by 0.58 years for every daily flight of stairs climbed — i.e., the stairs between two consecutive floors in a building.
