Smelly smells that smell .... smelly😂

So, I'm a CNA, and for any of y'all out there who work as one in a SNF or in home health care you ladies know all the treacherous stenches we smell on a daily basis to help keep our residents/patients clean. So after being around these smells all day I'll stop to go to the bathroom, and I feel like my crotch smells like all the nasty smells I've breathed in previously, few hours, few mins ago etc. Am I crazy for thinking this or is this an actual legit thing??
