Not just for cold and flu season....
I start acting like Monk when I realized the in my unscientific observational polling that 50% of men do not wash their hands after using the restroom. I'm serious, it's pretty nasty. I try not to "hit the head" at the same time as any male traveling companion because-
1. It can look a little, well you know...and,
2. I don't want to know which colleagues or co-workers don't use reasonable personal hygiene.
You know all those paper towels on the floor by the door in the restroom? I'm not they only one who's noticed this...
I carry hand sanitizer and wipe everywhere. And no more mints from the bowl or free samples at the supermarket.
