This video is Dr. David Price from Weill Cornell Medical Center in New York City, he is a heart and lung transplant doctor, however, during all the Covid-19 cases in NYC he is only treating the worst Covid cases. He has experienced various ways that people have contracted the virus. He also helps with our fears and has a very simple way to prevent getting it.  There are times the video signal is lost but hang in there, they get it back! It's quite long but worth it. Besides, what else do you have to do?
