More than I can remember. The same with the new Ice Age, Ozone depletion, Population Bomb, Alacar Scare, and many more that didn't pan out. I don't believe any longer there are experts in any science field. I believe they now exist to create scary scenarios to continue their grants.
The biggest disappointment has been the medical community. They used to live by high moral standards, not so much now with this Wuhan Flu. I would never have thought that profits would supersede proven therapeutics, and the Vaxx proponents are still ignoring many proven studies. Now Fauxi is pushing Pfizer on our children. I'm too old to be a revolutionary, but where are the younger men to defend our children?
My cardio asked me if I smoked. I said- no. He asked if I drank. I said yes. Socially , he asked? No I said. He looked at me. I explained that before bed, I take 2 vitamin supplements and drink it with 3 ounces of red wine- in one of those empty plastic applesauce cups. So— I am drinking, but am alone, so it isn’t social.
