Exercise is still really important for over-60s, and its important retirees do not write it off.
Regular, moderate exercise can go a long way to reducing the risk of developing dementia, according to diet and fitness expert Rosemary Conley CBE.
"We should try to exercise moderately for 30 minutes every day - that's my recommendation, she explained.
There are plenty of other benefits for exercise over 60. "[Walking] will help to keep your weight down, will help to keep your body mobile and help you to hold onto your muscle strength, which is all important as we get older," she added.
Ms Conley recommends activities that enable over 60s to socialise, such as a fitness or dance class.
She also suggests keeping active through everyday activities, to keep muscles supple. Carrying shopping bags and walking up stairs are both great ways to keep fit and maintain muscle tone.
