Why wear a helmet or a seatbelt (that don’t work) if you can wear an amulet (that always works!)? If there was an amulet against COVID i bet it would be a huuuuuuuuuge hit and make lotsa money!
same situation in Zanzibar. It is packed with tourists and everyone is happy. Oh, and can you believe it - no morgues filled with bodies and no hospitals overflowing with CoVID patients. Strange innit?
