Actually, keeping in good health is very simple. For us mortals, nature cannot be like a hermit, but life is only a few decades. This is the most natural way to keep healthy. If you can't do this now, you need to use some external forces, such as drinking scented tea in spring and green tea in summer. This can play a good role in the aftercare of your body. In addition to diet, you can also exercise properly, play basketball, swim, climb mountains with friends, go out for an outing and so on. And try to find more time to do things that make you happy. I believe you can finally sum up the best fitness method that suits you. Bless you!
