Why are humans the only species that puts shame on everything natural about ourselves?

u dont hv to go far back - around 18 century - how human stink and smell. that how the perfume industry and toilet industry became such a success. we get used to the new scents and toilet seats and tampons and since then, whatever was of the old days became taboo. its the embarment that is innate within us thats causing this. so goodluck do what we like to do for as long as it doesnt offend others
