It's interesting what ppl value and are willing to take risks for. We live in a gated community, about 300 flats, half empty, so about 3-400 residents. We have a pool and a gym. Both by booking only and max 4 in the pool, 2 in the tiny gym.
We have not had any covid instance as far as we know.
I feel totally safe with both, especially as I we are totally alone with my son in the gym and mostly the same for the pool.
We have had pre-made meal first time since jan. But even before that it was months between takeaways.
I had a much lighter workload so I was the one getting stocks/supplies. Mask + gloves + wash/quarantine everything that comes in the flat. It turns out to not be that much of a bother, so okay with keeping to it.
Instead of thresholds I put measures at the forefront.
IF school made masks mandatory + halved the classes somehow I'd send my son in
IF fencing club allowed masks + own equipment my son would be there already.
IF I could see ppl being careful (mask, distancing, cleaning) I'd go on holiday/away from the house.
At around 100/100k cases I wouldn't do these even if the measures were in place.
