The Genetics of Full Professors

I am reading "At the Helm: a Laboratory Navigator" by Kathy Barker. It makes a nice read for anyone who is planning a science career, specially an academic career, in the USA. It contains lots of useful as well as annoying advises for a new PI, but it also contains sharp witty quotes which are fun to read. I came across a funny section titled "The Genetics of Full Professors". Below is the image of the text from the Google books. So True!
