Exercise boosts brain power

If obesity, cardiovascular health, and more energy aren't enough motivation to get exercising, maybe throwing in more brain power will make a difference?

New research shows that exercise stimulates the brain to create new brain cells (and we could all use some of those) in the areas linked to memory and memory loss. 11 healthy adults participated in an exercise regimen for 3 months, and when scientists compared MRI's from before and after they saw definite positive changes. Armed with this new data, they're now looking to figure out which exercises have the most impact -- so doctors can prescribe specific workouts for specific patients.
