Buddhist views on health care products

In Buddhism, what goes around comes around, and the Buddha says not to kill, to live a long and healthy life. The relative cause of health and longevity is not killing. If you want to live a long and healthy life, you must have compassion. Health products, physical exercise, etc. None of them are good relatives, but they can be said to be karma. Just like planting melons, melon seeds are the intimate relationship between melons and fruits. Air, water, fertilizer, etc. It's up there. Without melon seeds, no matter how well managed, melons can't be planted. Similarly, if a person kills every day, exercises every day and eats the best health care products, it is impossible to avoid the coming of diseases. The other person is merciful and does not provoke all beings. He will never get sick if he doesn't exercise or eat health care products.
