I worked in aged care in full PPE during Covid.
I had no ice vest, but at least I was inside an office most of the time.
I felt sorry for the nurses, carers, food service staff & cleaners whose jobs required them to go from cottage to cottage in full PPE.

Another tip for at home:

Rinse a t-shirt under the tap.
Wring out really well.
Put it in the freezer until very cold but still soft, not stiff as cardboard.
Take it out and put it on.
Aaah. Bliss.

Start preparing a second t-shirt before the first one completely dries out.
Keep alternating the two.

Last time I needed to enter a university library there was a swipe card thingy at the entrance & I didn't have a student or staff card, but that's OK, I just tailgated someone. As long as you're not disruptive in any way, no one will ask questions.

They got rid of shopping centre benches during COVID so people couldn't sit close together. I don't think they put them all back.

I need to sit & rest often, & I struggle to find a seat these days. I'm convinced there are fewer seats than before 2020. I'm sure it's not just me getting older.

Libraries would totally be my top pick. Most of my favourite things in the world can be found in libraries.

Definitely still safer than the roads!

It just wants to get away from you. People only get bitten when they take it by surprise or deliberately provoke or corner it.
