Last night, in my sleep, I dreamt up a closed loop urine treatment system for a spacecraft. Pee was treated back to water, consumed by astronauts, and converted back into pee again.

When I woke up this morning, I badly needed to pee. That's when I interpreted my dream. All night my body kept signalling to my mind to go pee. My brain, instead, said "Ah, looks like pee is a problem. Let me engineer a solution."

Happy engineer's day, nerds 🤓
