I see your point, but I also raise you: if a test was available for any asymptomatic illness, and you could take it easily before engaging with a population whom would suffer if they contracted it from you, would you?

It's like an Intro to Ethics problem...and as I observed in that class during undergrad, the answer is not obvious.

[yardstick]

How often would you do this test? How many types of illnesses would you test for? Would you test weekly? Daily? Hourly? Would you lock your bedroom door and test every time you left it. Don’t even get me started on much resources would be required for the world to continuously test this way. Maybe someone ends up making a smart watch that continuously samples every few minutes? Where’s the threshold for sensibility?

And for what? Covid is no longer the covid of 2019. It’s not the same threat.

This isn’t about theoreticals, this is about getting back to normal. Which is not testing for relatively harmless things like covid (now we have vaccines and other meds being developed to help with the symptoms), cold, flu, etc, especially when vaccines exist. Just use your common sense.
