"What else was taking up his time?" Critical listening to others, building and being part of a community of practice, developing and challenging research students. Possibly informal communication, although I'm not sure of that. Teaching. Basically dialogue rather than written papers. Downvoters: please specify your knowledge and experience in academic research. I know what mine is.
