That's why I don't drink water - fish crap in it.
Ah, you're probably in that medieval mindset like me... drink beer instead of water. Of course the water was so bad in those days, (contaminated with horse urine, cattle slurry, human sewage, dead animals) that they drank beer and beer alone since the brewing process killed off nasties in the water. Although I gather the daily drinking beer (for children, women, everyone) was weak in terms of alcohol content, generally about 1-2%, hence the term "small beer" for something insignificant. The men brewed a stronger version for socialising and leisure. It's a nice thought. Everyone walking around
just gently pissed.
