3) Fletcherism
Horace Fletcher (1849-1919) was a man that made a frig load of wonga from the desperate fatties of the world. He became known as “The Great Masticator” (LOL) with the catchiest of catchphrases — “nature will castigate those that don’t masticate”.
His grand idea was that food should be chewed 100 times per minute before being swallowed. He said you should even chew liquids. Idiot.
He toured the country and spoke about his “technique” and bagged himself millions of dollars. People are a weird bunch aren’t they?
