Tetanospasmin
And Clostridium as well
Not a tasty lunch

A special neurotoxin haiku. A cup of Clostridium botulinum would be sufficient to depopulate the earth. What a cheery thought.

That would make it equivalent to about 2.5 mime artists or buskers.

People inject it (botulinum, not the mimes) into their face to keep wrinkles at bay. Stuff it up, and your problem with aging will be comprehensively fixed.

Cheers
