Really? Do we really need posters all over the place teaching us how to wash hands? I am talking about pre-covid too…

Are we just getting stupider as a species
or
Are these signs making us stupider by not offering us the opportunity to use common sense?

I have a few more posters up teaching me basic hygiene.

And before any wise person thinks of asking me: Oh did you just see this poster? No. Was so low on my totem pole that I decided to give it some thought now.
