You give yourself? Merkel just advised the German government that 60-70% of Germans could ultimately be exposed.
I'm taking extra precautions because I have asthma.
60-70% could be exposed in Germany, OK, over what time frame?
I would give myself a high likelihood of being in that 30-40%; working hard to not occupy a ventilator if I can because I'm in a privileged position.
That's not how it works unless by "cautious" you mean wearing gloves and properly fitted masks and avoiding all unprotected human contact.
