Take a deep breath and watch this...
He's one of the two that discovered the HIV. If your immune system can fight off HIV naturally, I'm 100% certain your immune system can take on the Coronavirus.
This is why I hate the media. Instead of telling people to strengthen the immune system, they cause unnecessary stress and panic. Then tell people to get hand sanitizers and produce list of house cleaning products that allegedly kill the virus. That's bunch of BS.
FYI, don't use hand sanitizers, they're bad for you and the environment. Just wash your hands with regular soap, not the anti-bacterial soap, thoroughly.
Just exercise, eat healthy, have clean hygiene, and take some antioxidants. These are the keys...
