To make parents live a long and healthy life, the most important thing is of course to let them have a healthy lifestyle.
First of all, let them do a certain amount of moderate exercise, take them for a walk and exercise, and let them have a rest after exercise;
Secondly, we should provide them with adequate nutrition, including fruits and vegetables, animal food and coarse grains, and wish them a speedy recovery;
Finally, we should try our best to reduce their pressure, avoid being too emotional and keep a calm mind.
At the same time, due to the deterioration of the brain function of the elderly, we should also provide them with more related activities and let them participate in meaningful activities to maintain their brain function, increase the amount of psychological activities and contribute to their health and longevity.
I hope your parents can live a long and healthy life. Bless them!
