tl;dr: Bodily Oddities is a browsable catalog of 143 human bodily quirks, reflexes, and perceptual phenomena—things like jamais vu, aphantasia, the Linburg-Comstock tendon variation, and "call of the void" intrusive thoughts. Each entry is filterable by body region, kind, or tag, and includes prevalence estimates plus a note on whether it's harmless. There's also a dedicated section for phenomena that alarm people but are medically benign.
