You’re right that it’s a marathon not a race. But isolating the vulnerable (on a semi permenant Basis) is not easy or good for these people. With good testing infrastructure and contact tracing, we can minimise harm. We just have absolutely no definite idea who are those who are otherwise healthy who are going to end up hospitalised (say for my age group 30-40 males it currently looks like 1:500 will end up needing hospital support) and that’s even before you look at those who may do fine without hospital but still be carrying some serious consequences (ie original poster’s partner).

I for one would like to avoid getting this altogether
