Do long in the tooth programmers get drawn to neuroscience?

I've been a professional programmer for 13 years and studied electronic engineering at uni. In the last few years I've developed this urge to learn more about the brain and neuroscience even though biology and medical sciences have never interested me in the past.

I think after programming machines for a long time the natural extension is to want to learn more about the "computer" inside one's head. Is that a common feeling or just me?
