That’s the least important point of his ignorance. It’s the fact that he’s allowing himself to be a host for the virus to not only pass to another but to allow a variant to be created. He’s an absolute idiot.
Day 161. Tonight after dinner I spent ten minutes hitting 7-iron shots (indoors, off a mat, into the net, real balls). The rehearsal and full swings were slow, with the intent that if it were outdoors, I'd hit the shot about 100 yards.
This proves he's an idiot and not a "scientist". Just enough information to be dangerous to himself and to others.
Just because you are young does not guarantee you will be fine. He just happened to be one of the lucky ones.
