I'm just not feeling it today for heavy medical commentary, so I offer up this apocryphal Bono story which always makes me smile!
Allegedly, U2 was playing a concert in Glasgow, Scotland when Bono asked the audience for total quiet. In the silence, he started to slowly clap his hands, once every few seconds. Holding the audience in total silence, he said into the microphone, "Every time I clap my hands, a child in Africa dies."
A voice with a broad Scottish accent, from near the front of the crowd, pierced the silence ...
"Well, fookin' stop clappin' then!"
