Take a glass and pour your favourite spirit, then see if you can smell it. If you can then you are halfway there.
Then drink it and if you can taste it then it is reasonable to assume you are currently free of the virus.
I tested myself nine times last night and was virus free every time, thank goodness.
I will have to test myself again today, as I have a headache, which can also be one of the symptoms!!!
Very good Johnny but that's a variation of an old joke by Tom O'Connor. His version;
A man of 89 went to see his doctor as he had heart trouble and wondered if he could have a transplant. The doc said that at your time of life, that would be too stressful. The best thing would be to have a large whiskey before you go to bed. The guy was telling his friend about this, and friend asked him if had worked. Oh yes, he said. I went to bed 8 times yesterday.
