A new and easy test for Covid-19 is doing the rounds; and it's simple, quick, and positive--or negative, if you see what I mean.
Take a glass, and pour a decent dram of your favorite whisky (rye--or gin or rum) into it. Then see if you can smell it. If you can, you are halfway there. Then drink it; and if you can taste it, it is reasonable to assume you are currently free of the virus.
I tested myself 9 times last night and was virus-free every time, thank goodness.
I will have to test myself again today though, as I have developed a headache, which can also be one of the symptoms.
