Deodorant as a concept is kinda wild cause like for 99.9% of human history we kinda just smelled like humans and no one was particularly bothered by it and then suddenly there's a strong societal pressure to buy a whole ass product regularly to prevent it??
I mean I know perfume has existed for a long while but afaik it was mostly a product for the rich who didn't believe in personal hygiene and was meant to mask the delightful scent of not showering for a month, not some mild sweat accumulated since the morning shower.
Idk, the whole thing smells kinda like a scam to me
