Exercise: It's the Smart Thing to Do!

After the age of 24, mental agility begins declining, so what can we do to keep our brain sharp into old age? Exercise!

That's right, physical activity can actually increase mental agility and memory while also increasing youth hormones.

A study in the Journal of Aging and Physical Activity concluded that strength training increased people's working memory span. The higher the level of resistance, the more memory improved, suggesting that strength training not only benefits the muscles, but the mind as well.

Trying new things every day also activates unfamiliar areas of the brain and with the new challenges, comes a better working brain. Researchers at McGill University in Montreal suggested taking up the tango because it involves more complex moves and thus activates more parts of your brain.

In addition to weight training, studies conclude that you should maintain a healthy diet, social interactions and an adequate amount of sleep to keep your brain sharp.
