I disagree with your first point. If you are a conscious person that tries to know itself and you are not built so weirdly as to slip into mental distress, then I think there is little limit to what you can do with your brain, and by extension, little limit to the fun you can have doing so. I realize the vast majority of people can't even imagine what that feels like, but I think that is partly due to the children being fashioned in a way very detrimental to free (roaming) thought. That can be fixed. About everyone else... I don't know. Your second point is interesting and I have never considered the issue like that. Time to think ;)
