On top of inevitably making you a big ol fatty, a new study suggests fitness levels in older adults have a substantial effect on the strength of connections between the different regions of the brain. [quote]The study suggests that cardiorespiratory fitness improves long-term brain function in elderly people and strengthens neural connections. The researchers found that fitness level which is determined by how effectively someone uses oxygen during a physical activity had a significant effect in the strength of connections between the different regions of the brain independent of the amount of physical activity they did.[/quote] So being healthy doesn't only make you look good, and feel good. But it could also benefit your brain activity too. Build those healthy habits now! [spoiler]read: put down the fast food and exercise some.[/spoiler]
