Looking through one of those advertising-funded local newsletter things, I saw there was an ad for classes in the martial art of ‘sebek-kha’. Which I’d never heard of.
So I checked google and learned that it is an ancient Egyptian martial art, said to be founded by founded by Heru-Ur (Heracles), passed down over thousands of years by a secretive lineage of Egyptian priests, and now known only to a select few. Known only to one chap running classes in a church hall in Herne Hill, to be exact.
The whole thing has cheered me up immensely.
