I remember my mother mentioning once that when her father (French country) came to visit once in the 50's, she was shocked at how much he stank. She had become used to american hygiene and his total lack thereof was VERY noticeable to her.
Catherine of Aragon is said to have boasted that she only had 2 baths in her entire life- once when she was baptized and once when she married Henry VIII... maybe that's why the marriage didn't work out? lol
At one time, bathing was considered a pagan sin and the church railed against it. Of course, that may have been because of the common practice of communal, coed bathing... probably led to all kinds of fun and games, eh? But even the Romans, famous for their baths, didn't use soap. They rubbed their bodies with scented oils, then used a type of scraper to scrape off the excess oil along with the dirt and dead skin cells, etc. THEN they got into the water and soaked. Trouble is, that doesn't get rid of the bacteria in the moist creases, which is where most of our body odor comes from. Baking soda was unknown until 1843, although the ancient Egyptians used something called natron (which is mostly sodium carbonate) as a type of cleaning agent.
