As an undergrad, I used to have a huge thick bushy beard like Darwin/Maxwell/Castro. Then I realized I scared some people with it, while others were jealous 'cause they could not grow one themselves. I shaved it in gradschool, for professional reasons. Nowadays, cleanly shaven both for professional reasons and to avoid pricking my lady. "Ouch, your face is sharp! Please shave for me!" It is also important in bed, as you might guess...
