A new study published in Annals of Internal Medicine suggests that practicing the martial art tai chi can help older adults boost their memory.

The study took about 300 people with an average age of 75 who reported their memory was declining and had them take a test on cognitive function -- which the average score was 25.

Participants then practiced tai chi twice a week for six months.

The study found that their scores had improved by 1.5 points on average, suggesting more years of cognitive health before the decline into dementia.
