As someone who spent 30 years in the medical industry, I have something to share w/ you.
For those of you who fly and opt for the "pat down", you need to demand the TSA thugs change their gloves. I've been watching on the news how they operate. People are being searched w/ dirty gloves....gloves that have been in crotches, arm pits, touching people who may be ill, people who pick their noses. Do you want those gloves touching you?
These thugs are protecting themselves from you. You need to be protected from them.
In a hospital, nursing home, in-home care, or even labs, that would never even be considered an option. Gloves are constantly being changed and the old ones tossed.
DEMAND TSA CHANGE GLOVES BEFORE TOUCHING YOU.
