International health insurance customers might be interested to learn that even gentle exercise can be of benefit to older people.
Indeed, research from Texas Health Presbyterian Hospital's Institute for Exercise and Environmental Medicine found that older women's blood flow to the brain increases when they exercise.
The study followed 16 women aged 60 or over for three months and found that brisk walking for between 30 and 50 minutes three or four times a week can improve blood flow to the brain by as much as 15 per cent.
However, while walking, it is important to ensure that you have the correct sturdy and supportive footwear necessary for the terrain, Maria Castellina, spokeswoman for walking charity Ramblers, advised.
She added: "You should always make sure that you have enough layers of clothing to keep you warm.
"If you're going to be walking for a long time, take with you something to eat and drink so that you don't run out of energy."
