"Every 14 days: 480.2 seconds. That’s 8 minutes (!!!), 0.2 seconds. Congratulations! You’ve scrounged and saved, and you’ve managed to accrue enough shower-seconds to take an average American shower!
You’ve sacrificed your health, well-being, social life, and potential future job prospects, but you can enjoy a truly obscene amount of shower, guilt-free."
I'm a bit sceptical about the "sacrificed your health" part, I don't have any sources (which is always a good way to start a debate - joke) but I don't think much physical harm can come to you if you don't shower for more then 14 days. Sure, people around you probably won't appreciate it and will probably say something, but I do believe that not showering for extended periods of time is physically safe.
Do correct me, if I'm wrong.
