Why do cats like to smell your hands?

My cat EB is sitting on my lap right now. And, I'm typing around her. And, as I'm typing she is rubbing her head on my hands (claiming them, I suppose) and smelling my fingers. I am pretty sure that I washed my hands after dinner, so I don't think that I smell like food. Then again, as a mom, I'm always washing something or have some kind of chemicals on my hands. So, maybe she is interested in those smells. Do you know why cats like to smell the hands or rub their head against your hands? Does your cat do that?
