My body is a temple. It requires frequent animal sacrifice.

But why are the sides of my head called temples? The part of the skull, marked by the temporal bone and covered by the temporalis muscle, is called the temple. Hairs on the temple turn conspicuously grey with ageing. The names temporal and temporalis come from the Latin word tempus, which means “time”, and greying of hair marks temporal progression, i.e., the passage of time.
