A leech, a bedbug and a mosquito go into a bar.
They all order the same drink and, even though they have to pierce the skin of their prey in order to sup, all leave with their thirst quenched. Their victim is none the wiser.
The barman enquires, “How’d you little devils manage to stab that poor blighter without ’em noticing?”
None of the three can speak English, or any other human language for that matter. That would be ridiculous. Do keep up. Anyway, they nonetheless answer as truthfully and honestly as they can – by drenching him with their spit.
Once we synthesise the anaesthetic qualities generated in such saliva, the brief painful prick of the needle will be a thing of the past. More importantly, this breakthrough will aid in any number of operations and treatments, helping ameliorate or even eliminate the suffering of countless patients.
As in so many other cases; if you want to find the next great scientific advance, look to nature.
Solidarity, brothers & sisters…☤
