Boston: Walking or jogging can enhance memory and cognition in older adults, according to a new study. The study examined the relationship between physical activity, memory and cognition in young and old adults.

The study by Boston University researchers included 29 young adults (ages 18-31) and 31 older adults (ages 55-82) who wore a small device called an ActiGraph, which recorded information including how many steps each took, how vigorous the steps were and how much time it involved.
