If you go to Ireland, and kiss the Blarney Stone could you contract Covid?

Yes! Who knows where those mouths have been.

Not if you wipe down the spot you kiss with rubbing alcohol and then apply hand sanitizer to your hands, and wear a mask whilst not kissing and keep your distance at all other times.

My Mother, who was a germaphobe, did kiss the Blarnehy Stone, and told me it was disgusting. Even so, she had to do it. She traveled a long way.
So I suppose it’s possible under the right conditions.

Sure, if the person standing next to you has COVID.

Aww hell, I’d do it in a heartbeat. They’ve been doing that for centuries in Ireland. Brings good luck. Covid Shmovid.
