One of the statistics that I remember from the book is that certain groups of people had a higher survival rate with certain viruses. People who ate meat seemed to survive at a higher rate. Thus the upper class. Viruses rob you of protein and resupplying protein is helpful. Some viruses attack the heart ( and heart valves) so fast there is not much hope. I think it was the swine flu in the 1800's that could kill a healthy train car full of passengers in one hour if an infected person got on board when the virus was hot.
That’s quite interesting about the protein. Also, don’t know posted the bit about oregano oil but I think I’ll get some.
