Good news for skiers: A University of Illinois study suggests that exercise strengthens more than your muscles. It also promotes brain growth. Data collected from the study shows mice that ran increased their brain’s capacity to learn and retain memories while mice that ate well but didn’t exercise did not see brain growth. What does this mean for skiers? Now when you tell your boss you're taking a "mental health" day to go skiing, you're not lying.
Research shows that physical exercise builds up your muscles and your brain.
