        Definitely going to question someone’s “propagation velocity of their actions potentials” next time I want to imply they’re stupid.

          I know you’re joking, but it’s really a kind of reasonable mistake to think of a nerve as an electrical wire conducting a singnal at ½c. It’s wrong, but it’s also completely understandable. I wasn’t trying to imply they were stupid, I just happened to see this factoid in the last several months, and thought I could correct their innocuous error. ^^;

            Not only was I joking, I thought it was impressive you even know what that is because I sure as hell don’t, it’s great you mentioned it, that’s the kind of awesome info I know will keep me coming back here. Cheers.

      Speed of light in cables and fiber optics is about 2/3 the speed of light in vacuum. If it has to jump some electrochemical synapses, it brings it down to much less than that.
