Exercise not only keeps your body trim, it can also keep your brain young. Staying in your 40’s mental functioning naturally drops off, making it harder to remember phone numbers, for example, or to multitask. But, base on the recent study, aerobic exercise for three hours a week can slow the decline which used MRIs to train brain function. There were payoffs for older adults too; those who work out three days a week for 15 to 30 minutes were less likely to developed Alzheimer’s.
