If you guys want to keep piling on advice to this young man in UK, I have a friend who concurrently did both his JD at Duke Law while doing in PhD in History/International Relations at Duke Graduate School. He got both degrees.

However, my friend's over his lifetime (he is nearing retirement now at age 58 or 59) career path has not made as good use of his sterling education as could have been the case.

Charting a direction that will logically be reinforced by one's advanced education is critically important.
