I’ll have a steam, a facial, a french mani-pedi, and a massage.

I’ll pass on the fermented urine though. Some other time, perhaps.

Who thinks up uses for urine? And fermented urine to boot!

There’s an anecdote about the Emperor Vespasian; his son (and eventual successor) complained about the imperial tax on urinals (at the link there’s a photo of one of Vespasian’s public urinals, which is still in use); the emperor produced a coin and asked his son to smell it. “Does it smell?” “No.” “That’s odd — it comes straight from the urinal.”

Urine was used by fullers for wool processing, among other things.
