By the way, here’s a relevant little problem for you.

There are three doctors and one patient. Each of them could be infected with the coronavirus. There are only two pairs of gloves and four masks. The doctors need to perform certain procedures on the patient one by one, for which all doctors need gloves. Masks were put on all four, but there weren’t enough gloves for the three doctors—there are only two pairs. You need to come up with an algorithm where no one will infect anyone else. Not doctors from the patient, not the patient from the doctors, nor the doctors from each other. (In this problem, the coronavirus has mutated, and it infects by contact with hands).
