In ancient times and places where potable water was scarce and people drank alcoholic beverages for substance, how were the people not dehydrated and hung over all the time?
You can sustain your water hydration with a 5% beer easily if that is all you drink. Your liver won’t like it, your kidneys won’t like it, probably your stomach and digestive system but you can sustain off beer for at least 10 years so far….
