Curioso!

Curiosity killed the cat,
satisfaction brought it back

The saying originally was “care kills a cat,” and began in the 16th century. Care was a warning that worry is bad for your health and can lead to an early grave; the phrase was a recognition that cats seem to be very cautious and careful. Over time, the word care evolved into curiosity.

For me it is related to Schroedinger’s cat, the curiosity of the experimenter kills the cat, or lets it live… Actually curiosity does not kill the cat, it sets it free.
