"The exercising of weapons putteth away aches, griefs, and diseases, it increaseth strength and sharpeneth the wits, it giveth a perfect judgment, it expelleth melancholy, choleric, and evil conceits, it keepeth a man in breath, in perfect healthe, and long life." – George Silver (1599)

So yesterday while with Miles, I mentioned this old book I had read in the context of headbutting, namely “Secret Fighting Arts of the World” by John F. Gilbey.

Miles had read it too and remembered the story about the “dinky little poke” which was this “secret technique” where a precise shot (aimed thru hit up thru chin to cerebullum?) would rattle the brain and cause KOs. The book also has a neat one about someone weaponized breath and one with a Kiai master.

This guy has a whole series.

The weapon of Dennis the Menace with the deadliness of David and Goliath.
