Yes I like that 'quirkyness" about science.
I have worked a lot in fragrance and have a couple of friends in the industry.
You might find this even more amazing.
I heard about the research originally being done at Sydney University

Dogs Smell Cancer in Patients' Breath, Study Shows

Dogs can detect if someone has cancer just by sniffing the person's breath, a new study shows.
Ordinary household dogs with only a few weeks of basic "puppy training" learned to accurately distinguish between breath samples of lung- and breast-cancer patients and healthy subjects

Can your nose smell the early signs of schizophrenia?
According to researchers at the University of Melbourne it can.
They’ve found that your ability to correctly identify smells on a scratch and sniff test can be an indicator of your risk of developing schizophrenia.
Zinc supliments some say help the sense of smell.
Does schizophrenia involve a lack of zinc?

Sex, smell and the contraceptive pill
Friday, 26 October 2001
pills
Italian scientists have found that the contraceptive pill makes a woman less sensitive to smell at ovulation time — and they're wondering whether this in turn may affect her libido.
Their study, involving 60 women aged 18 to 40, is published in today's issue of the journal Human Reproduction.

It is well known that women who live together tend to eventually syncronise their ovulation. Is this done with smell?

The sense of smell is probably the very first sense to evolve in a living creature. Back in the early days of evolution when we began as single-celled creatures, our sense of "smell" told us what was safe to eat. All living creatures have a sense to detect chemicals in their immediate environment.
In the more complicated animals, the sense of smell is used for other aspects of behaviour such as finding a mate, synchronising menstrual cycles, and communicating with the other animals in your group. Women can tell (by the smell of swabs taken from the armpit) who has been watching happy or sad movies (men are not so good at this). A breast-feeding baby can differentiate the smell of his or her mother, from any other nursing mother. Dogs and horses can smell fear in humans.

In the past we’ve had very limited tools to predict whether someone is going to develop schizophrenia or not. All we’ve been able to use is family history and certain behaviour. Until now.
Researchers at the University of Melbourne have found that our sense of smell is turning out to be very useful in predicting the development of schizophrenia. Take a teenager already at risk of developing schizophrenia. The worse they score on the scratch and sniff test, the higher their likelihood of developing schizophrenia.
