For elderly people who still wish to engage in some kind of sport even in their old age, golf is a relatively low-risk activity. There is no strenuous physical activity involved, and the pace of the game is not too stressful. Long bouts of walking on a golf course can also do wonders for their health. It improves blood circulation and strengthens the knees, reducing the risk of knee problems. The constant twisting and swinging also helps to keep the muscles flexible and the bodies limber. Mental alertness starts to decrease more rapidly in old age. Playing golf helps the elderly to practise their concentrating powers and mental sharpness. This is helpful in keeping mental illnesses like dementia at bay. Aside from physical and mental health benefits, playing golf also gives old people an excuse to go out and mingle with others. This allows them to feel young and sociable, improving their overall sense of well-being.
