I saw this picture on the wall of the gents toilet in a corporate workplace (company name removed)…a bit like a paint colour chart but for your micturition. Interesting idea to get the staff drinking more! Made me chuckle…you’ll be pleased to know I took the photo once I ensured there was nobody else present!
I was reasonably well hydrated at the time…and I didn’t even have to aim at the paper on the wall to be certain of the match!
