Scary future,possible epidemics,war,climate,tribal politics,etc,but we can only hope.The world has been on the brink since since the cold war in reality,remember the Soviet Lt.Col commanding a ICBM brigade rec. launch codes and holding back knowing it is prob. equip. failure as just one of several "close calls". As for diseases, the future Covid vaccines are trending to being in a easier more effective nasal mist and I believe a MNRA flu vaccine is being developed. As for the BS around anti-vaxxing,I still can't believe so many resisted a simple shot,I swear the reason some people refue things due to their Constitutional rights are being contrarians just because they can."It's my right to say no",so they do and get off on it regardless of data or truth or common good.
