<p>Hm, that’s funny - I got it as a second year graduate student myself, and I thought it would be <em>easier</em> because I’d already established a line of research and settled myself in with my advisors. I’d also proven myself with a year of graduate school. Most of the people I know with one also got it in graduate school, but of course that’s just anecdotal data.</p>
<p>Interesting to know.</p>
