True. cold water also opens your pores, for deeper cleaning. Years ago. I was told to continue lathering up your hands for the duration of “Take Me Out To The Ballgame”, which I still do, especially after working out at the gym.
So far this year, no cold or flu. I get the flu shot at my annual physical in the beginning of November. I’ll be flying at the end of the month and I’m hoping the flu will have run its course by then. If not, I may wear a mask lol!
