Well scientists aren't exactly up to that level, but they're apparently getting close:
A chemist and a nose specialist have just invented a new compound that turns manure's stench into a "pleasant smelling" odor.Do read the whole article, but my favorite quote is this one:
Manure smells so revolting because there are at least four groups of components that release smelly fumes: volatile fatty acids, ammonia-related ingredients, phenolic compounds and sulfur-containing malodorants.
Researchers are not yet certain why humans find these smells so disgusting.
I guess shit is the epitome of empirical knowledge and circular reasoning. It stinks because it stinks ... I can't think of another reason why I'd find it revolting.
TAN blog's the shit, other blogs are shitty [TAN]
