Hand sanitizer worship. That stuff actually kills a very low percentage of bugs, and generally only the weakest ones. which keeps our immune system from getting work against the easy targets and makes sure we only get exposed to the strong ones our now weakened immune system can’t handle.
Mega BUMP!
Our bodies have amazing capacities to fight off the bad guys. If you use hand sanitizer on a regular basis, the body's ability to fight is lessened.
I purposefully do not use hand sanitizer because I figure my old bod needs all the help it can get.
