Here's a Non-invasive Covid-19 test you can do at home.
1) Open a can of cerveza (beer for you Gringos) and try to smell it.
2) If you can smell the beer, drink it to see if you can taste it.
3) If you can smell it and taste it, this confirms that you don't have Covid-19.
Last night, I did the test 19 times and all of them came back negative. Tonight, I am going to do the test again because this morning I woke up with a headache and feeling like I'm coming down with something. Follow the science!
