Gut instinct:

- More likely to strictly adhere to the lockdown - Post recovery / quarantine period, if (big IF) you now have immunity and aren’t risking infecting others anymore, you could be more productive in the world.

- Helping others with their food/supplies/whatever. Heck, even spending more money on take out food which helps the economy.

The idea of building up a herd immunity seems to me to require knowing who has the immunity so we know when we have enough.

Get a blood test. If CRP raised and lymphopenic, likelihood of ARDS requiring ITU admission is higher. This can happen very quickly after the first week, so I'd put pressure on the doctor to keep me hospitalized.
