"...look around at your colleagues and tell me honestly whether you think they’re hot..."
The field may never be considered sexy or hot but please don't extend it to the people who are in it.
Sorry to disappoint, but 3 of my female colleagues are among the hottest women I've ever met. Smart, successful, great to work with and easy on the eye. And before you ask: too late they're all happily married and no, I will not tell you where I work.
