Can you last a day without taking a bath?
Well, I have some work colleagues who can last a week without taking a bath or shower. You really don't want to know how they smell! Suffice it to say that you just don't want to cross their paths ja ja ja!!!
But there was an era in the Middle Ages, which has been referred to as "1,000 years without a bath." Bathing was rare in Europe at that time, largely because the Christian Church considered it a sin to expose the body, even to oneself. It was not until 1641 that soap was manufactured in England. Religion had become less oppressive, but government harassment in the form of restrictions and taxes on the soapmaking industry caused the soap business to develop slowly.
