<p>I would love to attain multiple PhDs throughout my life. At least two, at most three. One when I'm about... 30? Another at 40 and the last when I retire. Now, is this possible; is getting a PhD as overwhelming and exhausting as people tend to say?
The disciplines I want doctoral degrees in are philosophy, physics and history. In that order.</p>
<p>Edit: Also, lets assume that the money for the education is not a problem.</p>
