His doctorate is in Philosophy. Of COURSE a stint in the service was more valuable.
A Ph.D. is an abbreviation for "Doctor of Philosophy" It is not a doctorate in philosophy.
R.W. Trewyn's doctorate was in microbial physiology. His Ph.D. dissertation was "Methionine Biosynthesis in Saccharomyces cerevisiae: The One-Carbon Transfer Portion of the Pathway."
Hahahaha...no kidding! I knew a guy who got a degree in both Philosophy and Psychology, and spent the rest of his life doing tile and floor installations...something he was quite good at!
