What I said. e_e
It doesn't really have an age limit. Curiosity will override anything and everything. Maybe that is why it is so taboo, because it goes against what society dictates. And yeah, society will have the word on this. If you deviate from the norm, you are now officially a danger.
I don't believe in "Adults do this and kids do that". Curiosity should be a trait that is present at all times. That or you'll become another number, following what your boss tells you.
I guess it is easy to control if you aren't running around, dismantling everything in order to learn how things work. Scientists, science is the only playground for this. Sigh, cowardice is another matter entirely.
I guess alpha people call it cowardice because they see animals as "contenders", so, the smaller the animal, the weaker an opponent it is. Their pride tells them that beating on a weaker opponent is "cowardly". Heh.
