The more energy you use each week — the more physically active you are — the less your chance of Alzheimer’s disease.

A study looked at 876 adults over age 65 and used MRI scans of their brains before and after activities that ranged from gardening to cycling. Higher levels of brain activity were linked with improvements in brain volume and less risk of Alzheimer’s.

In other words, the more energy used, the bigger the brain.

Researchers believe that simple caloric expenditure, regardless of type or duration of exercise, may both slow the degeneration of neurons and increase the structures important in cognitive functioning.
