Well, I mean, the modern English are sort of descended from Vikings (Anglo-Saxons). Scots and Irish are still mostly Celtic though (I think) and those places are way cooler, so not sure this argument holds
Do you have a source for this? Cuz I keep encountering historians who say "The idea that people in [insert time period] didn't bath is a myth". I kinda just assume now pretty much in human cultures bathed at least semi-regularly, people don't like smelling like shit. Sure in ye-olden times they probably didn't do it as frequently as we do today because clean water a bit more labor intensive to acquirer but I think it's weird to assume even mayo-kkkrackkers spend 100s of years just walking around with fungus growing in the crotches.
