1. I was incorrect about Trump and his statement that disinfectants could possibly be used directly into the lungs. He did say that. The clear proof that he messed up on that one is his staff saying he was "taken out of context." Often when a spokes person says you were taken out of context you weren't.
2. On UV light. It is used as a disinfectant. It is also a two edged sword. The body cannot make vitamin D without U.V. light which is why WWII submariners were periodically exposed to UV lamps. The harmful effect of UV light has caused people to slather on sunscreen which does retard skin cancer and wear better quality sunglasses to prevent cataracts, but The use of sunscreen and more clothing coverage in direct sun, (which retards vitamin D synthisis) to prevent skin issues is also the reason doctors test for vitamin D on routine blood work and regularly recommend vitamin D supplements.
