I love philosophy, especially metaphysics, but frankly I feel like reading too much of it can make you lose sense of reality and start questioning everything. And the problem is that there are no answers, just questions! (Socrates: All I know is that I know nothing) For a programmer 1+1=2. For a Philosopher it doesn't always equal 2.
My philosophy teacher in college: a single, 42 year old pothead that puts makeup on and plays starcraft every day. First day of class he told us that taking coke while a teenager helped him find his "inner self". Very smart and awesome guy though.
One of my best friends from high school: took philosophy in college, did a Masters and now doing a PhD. Today he's a 33 years old virgin still living at his parents basement. Very socially awkward and struggles with depression. Awesome guy to talk to though.
I have tons of examples like these. It could be just anecdotal evidence, or there could be some degree of correlation. I have no idea, but I have yet to meet a philosopher with both feet on the ground.
