I know how many days in which I have just answered e-mail, had three phone calls and a two hour lunch. Poof, gone. They are not infrequent.
I have in hands, now, specimens of bottom from t he Gulf Stream, obtained by Lieutenant Craven, and I can say that they are among the most interesting that I have ever seen.
When I had no shoes I was comfortable - I used to run barefoot. When I wore shoes it was difficult. To run in shoes was ok, but at the beginning of my career it was hard.
