Want to stay fit and keep your dementia away? A new study  shows that you can keep dementia  away by just four minutes of vigorous exercise.

If you are given the choice of the stairs or an elevator (or perhaps a cable car), consider taking the stairs

Less than 4 minutes of physical exertion a day – such as rushing for the bus or carrying heavy shopping – could halve your dementia risk. People who engaged in short bursts of vigorous movement were up to 48 per cent less likely to develop the condition than their sedentary counterparts in a large study.

“These brief bursts of higher-intensity daily activities are in every nook and cranny of our day-to-day routines, so this creates a really exciting and viable opportunity to find new ways for the everyday person to protect their health,” says Nicholas Koemel at the University of Sydney, who parks his car in a distant space when he gets to work so he has to walk further.
