“Doctor, how does my knee pain relate to playing the saxophone?” ?

A man comes to a famous doctor and with a suffering grimace on his face begins to complain of severe pain in the knee. The doctor carefully examines him and says:

- Sorry for the strange question, but do you play the saxophone?

- What? How did you know? Yes, I do.

- Oh, that's it, love. I advise you to stop your classes immediately if you do not want to lose your leg.

- Doctor, how does my knee pain relate to playing the saxophone?!

- Just trust me, love. I'm a doctor, I know better!

- All right, doctor, I'll stop... the man says with a sigh and leaves the office.

After the patient leaves, the young nurse addresses the doctor:

- Ivan Petrovich, you will forgive me, but what is the connection between a sore knee and playing the saxophone? I can't understand it at all...

- There's no connection here, love. This man is my neighbor on the top!
