Just when you thought the coronavirus pandemic could not possibly suck the joy out of life any more, along comes another study to prove you wrong.
Boffins in Sweden have found singing the Happy Birthday song could potentially spread the killer virus. It's all to do with the way we pronounce our Bs and Ps - and the study was inspired by fears choirs singing together could be sparking outbreaks.
Or pronunciation of said consonants are believed to release larger droplets from our mouths. If a person is infected, their the P in 'happy' and B in 'birthday' would see them spread the deadly bug further.
Scientists in Sweden studied the amount of particles released when people sing in order to understand how it affects the spread of Covid-19.
