Please explain your second sentence. Who knew or didn't know what?

Even though I have rarely taught it to my kids, they all know how to cook. I remember that my paternal grandfather has never known how to cook while everyone else knew. Moreover, he has never been able to eat anything spicy while I believe that kids could. Maybe people are able to do things out of curiosity and because they are not afraid, so they try and in the end, they manage to do it.
