Golf Studies.<p>* Income, outdoor lifestyle, opportunities for travel. Good phd topics across economics, law, environment and civil engineering. And, you make (some, admittedly very poor dress sense, I mean those shoes...) people happy.<p>Look, it's bizarre but even actuarial studies can be immensely rewarding. Who knew statistics on when and how people die was so fascinating? It's impossible to say a priori which field of study "is the best one" because taken seriously, <i>they all are</i>. It depends who you are, what drives you, and your capabilities latent and overt.<p>Now law. That's where great minds go to die.<p>When I was at uni I thought it was arts. That was the 80s. I've had a great life, fruitful, fun, fulfilling and well renumerated for over 40 years from studying computer science in a tiny British post 1950s redbrick university.<p>I am not sure I'd recommend that now.<p>The student debt crisis is economically stupid and an attack on the young.
