"My mind rests when I read books."
Translation:Mój umysł odpoczywa, gdy czytam książki.
The misleading hint has just been removed by our team.
The problem is that we don't have individual hints for every sentence, only for the whole course, and furthermore, there are shared hints with the Pl->En course, which featured one rare context where "my mind" = "zmysły". Stuff like that happens sometimes, sorry about that.
