Makes you wonder what Henry VIII's real problem was then? His
wives must have been some of the unluckiest women in England at
that time?

> Olfactory receptors can be traced back hundreds of millions of
years and are believed to be present in all vertebrates. Humans
have around 800 olfactory receptor genes, but only about half of
them are functional, meaning they’ll be translated into proteins
that hang out in the nose and detect odor molecules. But within
a functional gene, minor variations can cause changes in its
corresponding receptor protein, and those changes can massively
affect how an odor is perceived.

a neuroscientist at Monell Chemical Senses Center and an author
of the new study. “And we know that some people smell that
molecule as urine, some people smell that molecule as
sandalwood, and some people don’t smell it at all.”

evolutionarily recent gene variant found it more intense.

have extraordinary variety.”

> Individuals who assigned higher importance to olfaction or
engaged more in body odor sniffing showed stronger sexual
desire. We further explored these associations in different
cultures to determine whether cultural consistency existed. We
conducted a second study to make cross-cultural comparisons
between Indian (N = 313) and US
(N = 249) populations. For both countries, a higher
importance placed on olfaction and a higher prevalence of body
odor sniffing were consistently associated with stronger sexual
desire. In conclusion, our study confirmed that people who
placed more value on olfactory function or engaged more in body
odor sniffing showed stronger sexual desire. These correlations
were consistent for both sexes and across different cultures,
further indicating the importance of olfaction in sexuality.

I myself cannot stand body odour, and am disgusted by sniffers.
