My two favourite deformities: my simian crease, and my webbed toes.
To the superstitious man, my simian crease implies that my head and heart are the same thing. To the scientist, it’s a rarity associated with down’s syndrome. Tony Blair and Hilary Clinton reportedly have it too.
My webbed toes don’t actually make swimming easier. I’d rather be a duck than a frog. Stalin had it.
With these purely physiological mutations, I really was born this way.
