Up until his demise, my husband (TAO) never applied toothpaste to his toothbrush. Instead, he squirted a small amount into his mouth, directly from the tube. His strongly held theory was that manufacturers had steadily increased the length of tooth brushes, not to brush more thoroughly, but to increase toothpaste use and sales.
He was convinced and had some authority; having a father in dentistry. I learned that his father was a dental technician who, upon evacuating his family to a village in the hills around Lyon to avoid bombing during the war, promoted himself and hung a "Dentist" sign outside. Making TAO doubly qualified in all things tooth-related, as well as skepticism.
When one of TAO's grown daughters; with very beautiful, long, thick hair, visited us in California, years ago, she shared that she shampooed but never followed the recommended instructions to "Rinse & Repeat" as it was obviously a ploy to double the use of their product.
Having spent many years mucking out stables and grooming horses, I had many times seen dark water in my first rinse cycle and happily rinsed and repeated. Same Planet-Different Worlds.
I've been noticing a spate of TV advertising lately for "Whole Body Deodorant Products" that I not only find distasteful to see every fifteen minutes but has made me question the ulterior motives of the advertisers. There are words they aren't using in the ads but the visuals denote that humans must be stinky in every crack, fold and crevasse and so must purchase and apply their creams.
Every Human has a slightly different scent, depending on food consumed, lifestyle etc. I, personally, love the smell of skin that has been touched by sunlight and even a side of Hard Work.
Who am I to judge? Horses are my favorite aroma. Let's bottle and sell "Eau de Barn". Afterall, there's an aftershave out there called "Wet Gun Dog".
Just imagine that there's going to be a whole new generation of Search & Rescue Dogs
