Today I learned from my medical transportation driver that in her home country of Eritrea in Northern Africa, they do not use timepieces. Instead they stand in the sun and are able to accurately determine the current time based on their cast shadow.

I thought it was so cool that they are so in tune with nature in this way, eschewing mechanical/electronic timepieces with their relentless heartbeats.

Gentle reminder: an old 12cm CD and a slim soda can make an elegant portable #sundial.
On this sundial the noon hour line must face west.
