No I believe I along with my family have already been exposed to the virus with various interactions. We live in a crowded condo with central air and people piling on in the mail room. Everyone in the building including me ordering takeout. There is no reason for me to be in lockdown.
The risk has to be balanced with the rewards. So I wear masks when asked to and wash my hands often. And take the 1/1000ish risk of contracting covid a few times a week. Trusting that my low risk of it having lasting complications means that it costs me something like 1/million chance of really bad outcomes to resume most of my normal life.
