I am a scientist therefore I am logical.
I am a graphic designer and musician and so I am illogical.
I think of myself as intelligent, and I love math/science and geeky things. Intelligence is definitely a turn on; chat me up about Fourier transforms or P vs. NP or organometallic chemistry or black holes (or anything of which you are an expert) and I'll be titillated.
I am down-to-earth, hysterical, and fun-loving
