Think of it this way, say, as a professor and Ph.D. researcher in sports science, you spend literally your whole work day doing/thinking about how to train athletes and how to make athletes better. When you're not at work, you just wanna ride and race your bike. When you're at the track racing your bike or training, you don't "owe" anyone there a discussion about the latest training tips or training protocols, regardless of how active you are in that field in your day job.
