My facial hair, hair on top and other hair grows like it has been fertilized.
I could never stand growing a beard after 2-3 days. It was like having a Brillo pad cut in half rubbing my facial skin. 24/7. So no beards.
Now, I have a standing appointment every 4 weeks to have the hair on the top of my head cut and trimmed.
My wife is an RN and she went back to work after our kids got to be 10 and 12. She worked in a busy FP office.
After she started to work, I noticed that I was getting more colds and light flus during the local crud out breaks.
The doctor she worked for, had a mustache and seldom had the crud that apparently my wife was bringing home from their medical office. He suggested that I talk to the local infectious disease doctor and why he and so many IDs and busy MDs had full mustaches.
The ID doc said that a full and clean mustache apparently blocked or impeded the germs and viruses and ???? from getting into your nasal passage.
He said that I would have to wash, clean and dry my mustache several times each day and before I went to bed.
At first my wife was against it, and then I got the local crud that was going around and was sick for a week.
She, then said, “Grow one, keep it neat and clean and lets see.”
I had zero crud attacks the rest of that year and basically none the next year.
One of my wife’s brothers was/is married to a nurse, and he was having the same problem.
My wife suggested to that SIL to have her husband, my wife’s
bro, grow a mustache. He did and had the same good results.
The second bro was married to an office manager/lead receptionist in a busy business in a college town. He had the same problem, and he grew a mustache and had the same good results.
Another good deterrent is don’t pick your nose...not that there’s anything wrong with that :)
