Just like faster than light travel its one of those things you know is impossible ,red heads cant get sun tans they just go red and burn. However  now some boffins at the University of Arizona have come out with a drug which causes your body to release copious amounts of melanin allowing everyone to get the perfect all over body tan without the need of the sun and its dangerous effects . I ask what next.

[blakestyger]

A propos of nothing to do with tans but all to do with red-heads is the fact that they emit some sort of endorphin unique to themselves.

Now, in the interests of science I have stood as close as is decent to red-heads in an attempt to verify this but have never been able to; probably because I abused my nasal tissues too much when I was a bench-chemist all those years ago.

Has anybody else been able to detect this difference?

[Bored chemist]

I just bet endorphin isn't the word you wanted.
Body odour is, in part, related to the major histocomatibility complex. It also defines things like hair colour.

[SquarishTriangle]

Pheromone perhaps?

[blakestyger]

Sorry, yes it was a pheromone - not endorphin.

Lol I'd eat loads of those melonin making pills and turn myself black...wonder if people would recognise me though lol

Is this why redheads are so freckly?
