I've lately been looking into reasons for people getting PhD's, job placements and outlooks, income levels, etc. I'm doing this partly as a response to the question of "what have I done with my life these past five and a half years?" I'm also just curious what other people think on the topic.
Here is a nice discussion of a PhD holder and academic on his blog about getting a PhD in physics. His advice: get a PhD in physics because you want to be a graduate student for five or six years.
Well, this is advice I've never heard before.
