If you are asking what the reward for curiosity actually
is, it might be worth recalling the old saying: "Curiosity killed the cat." The suggestion there is that it's best to keep your nose out of business that doesn't concern you. Cats are especially curious creatures, always interested - when they're not sound asleep, that is! - in what is going on around them. The notion of the 'killed cat' probably implies that one got too close to something dangerous - a circular saw, perhaps? - and paid the ultimate price. The lesson for humanity is: Keep out of it!
So, there's one reward for curiosity!
