What is the use of enjoying health?

I knew from the beginning that it was because my parents bought their products and became members, so I paid attention to it to see what was going on. Only then do we know that they belong to the home-based pension platform, involving all aspects of the elderly population. Later, I found out that they also do smart wearable devices and travel for the elderly. At first, I just thought that when I was not at home, I could learn about my parents' health and enrich their old age through travel. I didn't expect them to have a health management project to guide the adjustment, and gradually their parents' physical condition improved, which I personally felt was ok.
