If you want to stay healthy and avoid the flu or at least get over it quickly, you need to have a strong immune system. That’s one of the reasons I train in Qi Gong every day. https://www.ageofthecloud.com/flying-crane-qi-gong.html
The established health system never ever talks about building the immune system. The ads on TV never promote preventive health and most doctors never give you ways to keep yourself healthy.
