Seems like. Been practicing again, and I can sense it is coming back. I left my hobby of trumpet playing when I did the doctorate, that was some 6+ years ago. Some part of life seems to be coming back. I took the hobby as a way of relaxing and having a bit of artistic engagement. So I would turn on the CD - play the minus one and belt out a tune from Duke or Chet. It was fun.
Now, I am having a bit of time for it. The missus proded to me to pick up my trumpet again.
This reminds me of my talk last month when I was in Spain attending a conference. I was sitting with a mixture of PhD students and professors all from various countries discussing the idea of doing PhD. We all concluded that one must be a little bit crazy to do this, specially if you do something in the field of mathematical logic or theoretical computing (which I did). You got to be extremely out of your marbles to attempt this. You have to be a bit odd with some loose screws to go through the process of not having a life. Because that is what you are going to experience while you are writing your thesis, you ain't got a life. You may also pass up some opportunities for good employment. That thesis becomes a ball and chain on you.
All of that said, I do feel I got some edumacation.
