31、the same amount of time So，even going for a walk every 2 or 3 days for just 10 to 45 minutes can helpThat should be good news for the elderly The effects of exercising on the brains of younger people havent been studied yetStill，it cant hurt to take occasional breaks and go for a walk or run around
