Ok, so I've seen people talking all the time about how "Ezio isn't too old because he's half TWCB"

Where exactly did this come from? Right, he's descended from them, I get that. How does that mean he's suddenly some superhuman? Why does this (pretty lame) excuse need to be made, as opposed to just acknowledging the fact that Ezio has been an athlete all his life?

Finally, if TWCB were for some reason so much more super (when we build robots, we tend to build them out of things stronger than us, don't we?), surely that "superness" would be massively watered-down to the point of not existing anymore anyway?
