I must admit that being called 'Doctor' is still something that fills me with joy, as its confirmation is still relatively recent. But as you prefer, John it is.
Being in academia is all that I know how to do, really, so I suppose I must still enjoy it, if I am still doing it. It is, admittedly, a challenge to try to persuade undergraduates that Victorian literature is relevant. I would think that astrophysics is a much easier sell.
