A month or so ago, I casually mentioned to my labmates that I can’t get enough of the smell of gasoline, and that I had stolen a whiteboard marker from our lab to sniff when I was particularly frustrated with research. This had two results: my labmates now tease me mercilessly, and I realize that not everybody is as enamored by these smells as I am.
The latter was quite an epiphany: I had imagined that everyone finds the smell of gasoline ambrosial. So why isn’t it true? Being a geneticist, of course my first thought was that it must be all in the genes.
