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!
