I'm a massive fragrance fan - I think fragrance is part of someone's hygiene, and I'm a big believer in leaving an impression through scent.
Rules governing defecation, hygiene, and pollution exist in every culture at every period in history. It may in fact be the foundation of civilization: What is toilet training if not the first attempt to turn a child into an acceptable member of society?
It is poor civic hygiene to install technologies that could someday facilitate a police state.
Ken, my husband, just smelled like he belonged to me. I'm not talking about hygiene. I'm talking about when you hug him, he either feels like a member of your tribe or not. It's their scent.
All mental hygiene is based on the core practice of doing nothing. Most of us are good at wasting time, staring at the wall while telling ourselves we should be working. We call this doing nothing, but our brains are furiously active. We think constantly, and our thinking is often rife with distress.
