Harvard researchers have come to some conclusions about how much exercise will protect you from dementia. They say people engaging in moderate to heavy physical activity are 45 percent less likely to develop any kind of brain problems.
In the study, activities were categorized in three categories:
* Light: standing and walking.
* Moderate: faster walking, housework, yard chores, climbing stairs and light sports, such as bowling and golf.
* Heavy: major housework and intense activities like jogging.
One way the study was different from others: It mainly focused on older people. Other studies included people of all ages. This study shows that even for older people, moderate exercise is protective.
