Scent Fundamentals

THE very word 'perfume' has feminine overtones to many male ears. Men can be sold 'deodorant' and possibly 'aftershave', but the idea of all those dinky little bottles with their fussy paraphernalia is too much for the sensitive male ego. Yet no industry can afford to neglect half its potential market, and perfume-makers are ever keen to crack the shell of male reticence. Now they may know how to do so.

It is known that appropriate scents can improve the mood of those who wear them. When a man changes his natural body odour, it can alter his self-confidence to such an extent that it also changes how attractive women find him. How perfumes work to make people attractive is not as obvious as it might seem.
There are three broad theories of perfume use. One is that people employ it to mask body odours that they perceive as bad. The second is that some perfumes contain chemicals that mimic human pheromones—elusive, mysterious (and possibly mythical) substances believed by some to play a role in mating. The third is that people use it to heighten or fortify natural scent, and thus advertise sexual attractiveness or availability.
All three theories could be true. In particular, the role of perfume as an olfactory disguise is obvious. Even here, however, there are some subtle twists. Bad smells are not just a matter of poor hygiene. Illness and old age both bring characteristic odours of their own, and neither state makes people more attractive. Perfumes may spoof these messages.
As to pheromones, whether humans have these is questionable. A pheromone is a chemical that elicits a specific behavioural response at a distance. Some insects, for example, can release sex pheromones that will attract a mate from many kilometres away. The most likely human candidate is a substance called androstadienone. This is a derivative of testosterone that is found in men’s sweat and is known, from brain-scanning studies, to promote activity in parts of women’s brains. That this results in changes in behaviour has not, however, been clearly demonstrated. In fact, they might exist but they do not function as an attractant. They will elevate one’s mood but not attract a mate.
The most interesting area, though, is the interaction between perfumes and natural scents that carry messages but do not have the specific properties of pheromones. Odours co-ordinate a wide range of human behaviour. Mothers can recognise their children by smell. Children can recognise each other. Relatives can be distinguished from non-relatives, even to the extent of understanding who is genetically different enough from the smeller to be a good choice of mate. The sexes themselves smell different, too, and women can glean information about a man’s social status from his smell alone.
As long ago as the 1950s, a perfumer called Paul Jellinek noted that several ingredients of incense resembled scents of the human body. It was not until 2001, however, that Manfred Milinski and Claus Wedekind of the University of Bern wondered whether there was a correlation between the perfume a woman preferred and her own natural scent. They found that there is.
The correlation is with the genes of what is known as the major histocompatibility complex (MHC). This region of the genome encodes part of the immune system. It turns out that one of the most important aspects of mate choice in mammals, humans included, is to make sure that your mate’s MHC is different from your own. Mixing up MHCs makes the immune system more effective. The MHC is also thought to act as a proxy for general outbreeding, with all the hybrid vigour that can bring. Fortunately, then, evolution has equipped mammals with the ability to detect by smell chemicals whose concentrations vary with differences in the MHC of the producer.
That means people are able to sniff out suitable MHC genomes in prospective partners. A woman, for instance, will prefer the smell of T-shirts that have been worn by men whose MHC genes are appropriately different from her own. Women, it seems, choose not the kind of smell they would like on a partner, or even one that might mask a nasty odour of their own, but rather something that matches their MHC. In other words, they are advertising their own scent.
There are many useful inferences that might be drawn from this research. One would be that a woman’s choice of perfume will resist the vagaries of fashion. This may explain why most innovation in the industry involves changes in packaging and marketing, producing all that fussy paraphernalia, rather than changing what is in the bottle.
Another implication is that it is probably best that people choose perfumes for themselves rather than for someone else—unless they happen to know what the recipient likes. If one has made a good genetic choice of partner (i.e. someone with a significantly different MHC), then the theory suggests that one should not be able to choose something that smells nice to them based on one's own preferences. One might, though, have better luck choosing for a close relation!
The research also raises the question of what so-called unisex perfumes are for. In any genetically successful love match, one of the partners ought to hate a unisex perfume. Perhaps, in a world of olfactory fakery, this is one tip for the wise. If one's partner has a strange knack of being able to pick out all the right perfumes, this may not be a good sign at all. And that, of course, means that the best one can hope for is that one's lover or spouse has bought you a perfume that you absolutely hate!!!!!!!

Just Imagining

is the process
of forming
mental images
or concepts
of what is not
actually present
to the senses.
We spend more time
in our imagination
than most people ever realize.
Within our imagination,
we create our ideals,
role models,
perceptions on love,
how to live & survive in life,
plans, goals,
ideas of pleasure, fun,
pain, insult, offence etc.
In other words,
we form our personalities
around our imagination.
On one hand,
we escape from
the harsh realities;
as in an imaginary world,
life is exactly as we want.
On the other hand,
imagination, as an escape from reality,
can become addictive and debilitating.
In dwelling too long,
we run the risk of
losing touch with
the real world.

Happy B'Day, Lily Allen!

Lily Allen Allen was born (on 2nd May, 1985) in Hammersmith, West London. She happens to be (for the uninitiated) a pop-singer, songwriter and a talk-show host who has a wide following, especially among the youth (inclusive of the teens & the pre-teens) in the U.K. as well as in the U.S. - and also happens to be my latest fancy.
Her hit songs like 'Smile', 'Littlest Things', 'Alfie' and 'The Fear' keep me alive and bouncy! She hits the notes with her confident yet sweet vocals. She is much talked about for the postings on her MySpace blog which often get her the controversy tag. This year she has also shot into the tabloid discussions for having been voted as one of the sexiest women of the world by the readers of FHM, the men's magazine.
Of late, Lily Allen has also taken an interest in environmental and social concerns, which is praiseworthy indeed!
Here's wishing her all the best & a fantastic birthday celebration!
