Interesting. I've noticed a lot of things like that too. Back when I was in high school, I switched to a certain type of Old Spice deodorant. I've never used cologne or any of that stuff, but apparently this deodorant did the trick. When I'd hug girls they'd actually tell me, "Wow, you smell
really good!" When I moved away from Virginia and back to Montreal, my friends from Virginia would occasionally tell me they missed my smell. Not just me...my smell! Of course, everyone's smell is different. You're constantly emitting small particles, releasing them into the air, and they spread very quickly through diffusion. You release body odour, the fragrance in your deodorant, whatever detergent you use to wash your clothes, and particles you've collected from places you go. It's very easy to tell whether someone ate lunch at Subway just by their smell.
So as a result, we have many researchers trying to find fragrances that appeal to our senses. Personally, I think most perfumes smell like crap, but apparently a lot of people don't agree with me on that one. What bugs me most is the advertising for perfumes, especially for the ones for men. I mean sheesh, the only way you could be any more direct is to actually have the narrator say, "If you buy our product, you'll have sex with hot girls." (Didn't Family Guy do something like that?).

I doubt it was his "skin chemistry," though that's a reasonable guess. Most of the odours, as far as I know, aren't very reactive. Like I said, it's probably a mix of all of the fragrances.

In a flash, my cloud-nine day came crashing down in an explosion of husky, bitter smelling crap. I asked him what he had done, what this new abomination was that made me want to tear out my hair, follicle by follicle. I think he said 'Chanel' something or other.

That's happened to me too. I ran out of my Old Spice, so I went on my "backup" stick of old deodorant. When I gave my morning hugs, people started saying, "You don't smell like...you."

1) Memory: Scent is the strongest sense tied to memory. With one whiff can instantaneiously recall as much as a whole chapter in one's life that had otherwise been forgotten! Even annually, scent, at least for me, brings me back to the year before. For example, I had to pick up my brother from school back in mid-October. I passed by a classroom who's students had been carving jack o lanterns and, as such, their classroom smelled of pumpkin. To me, that's the smell of Halloween. Freshly. Carved. Pumpkin. Mmmm. I wasn't one bit into the Hallowen spirit until that very moment.
I find I can even smell seasons. I can tell winter is coming, early on, bacause I can smell it in the air. Same with any other season. I also have what I call a "beach smell". During my summer Holidays, I go to Canada's west coast every year, and it my most favorite place on Earth. Sometimes I catch a hint of it in the air, even in Alberta. I cannot even explain it, but it is bliss.

this article, if it's not too technical. It explains a lot about the link between smell and memory. Here's a snippet:
Scientists have long wondered how we manage to remember smells despite the fact that each olfactory neuron in the epithelium only survives for about 60 days, to be replaced by a new cell. In most of the body, neurons die without any successors. But as the olfactory neurons die, a layer of stem cells beneath them constantly generates new olfactory neurons to maintain a steady supply.
"The riddle was, how can we remember smells when these neurons are constantly turning over and the new crop has to form new synapses?" says Buck. "Now we know the answer: Memories survive because the axons of neurons that express the same receptor always go to the same place."
In terms of evolution, developing a good sense of smell is extremely important. It's one of the only ways we can tell subconsciously if something is going to poison us or not. Generally, the things that smell like crap are things we shouldn't eat.
An interesting thing happened to me a few months ago. I went to go help my friend do some research at my school library, and on the way I stopped for samosas, which I was obsessed with at the time. I bought six of them, expecting my friend to eat three. Well, she had already eaten, so I ended up eating all six. That was a bad idea, considering that those samosas contained traces of fecal bacteria (generally, this is what causes food poisoning). Unfortunately for me, I only realized this later that evening, in the middle of a very good concert. I didn't want to leave, so every 10 minutes I'd run to the bathroom, puke my brains out, and come back for 10 more minutes of good music. It's the worst food poisoning I've ever had, and it still affects me in a weird way.
Samosas, which used to smell like exotic packages of love delivered by the gods, now smell like the worst combination of disgusting smells you could think of. Anytime I smell them, I just want to vomit. I can't stay near my friends when they eat them, or I'll start gagging. It's all because my brain has now associated that smell with food poisoning, and I'm subconsciously repelled by it now.

3) Attraction: I remember reading somewhere that people have distinct pheromones they let off, and others could smell them subconsciously. Depending on the 'scent' of the individual, you could instantly love them, or instantly hate them. (I don't know much on the subject but if someone has more info on this then please elaborate, I find it very interesting). I find, also, that a guy can be handsome, smart, charismatic, and funny, but if he doesn't smell right, or just plain bad, then I'm turned off to him completely.
On the flip side, if I see a completely average guy, who just happens to smell great, then I'm completely turned on to him.

There's still a lot of uncertainty in this area, at least with humans. Insects certainly use pheremones to their full extent, leaving trails behind them so other insects know where to go. We know it has
some effect on humans, but we're still not sure about the details. Some companies have tried to market "pheremone perfume," which is laced with human pheremones. In all tests, these turned out to be useless. The only major effect they may have had is the placebo effect of giving you confidence around girls (and this does have some major effects).
I stayed up late with some friends one night trying to figure out what the purpose of pubic hair is. We had no computer or books on the subject, so we just ended up talking about it all night, and couldn't come up with any solution. So the next day, I looked it up on Wikipedia, and apparently there's evidence that pubic hair has a lot of pheremone receptors. (Since I know you're all dying to know, the other reason for pubic hair is to provide lubrication).
But yeah, it's kinda disappointing to think that a lot of what determines our success is the smell that we can't even perceive (pheremones don't register to us consciously).
Anyway, maybe this makes sense to you, maybe it doesn't. If the science is unclear, I can try to simplify it if you want. I think I got a bit carried away...
