I, also, thought about the

I, also, thought about the potential for differences in the firing of action potentials among people. Once an action potential has been fired, does it travel at exactly the same speed? Do people with shorter legs have action potentials that reach the projection of the neuron earlier than those of people wiht longer legs? (probably a negligible amount anyway....)

What about processes of which we are not  conscious--breathing, blood-pumping, shivering? Do some people perform these acts at negligibly different rates based on action potentials? Probably. It doesn't seem like these differences would be worth noting, though, given how infinitely small they would be and the fact that an action potential is not something created by the mind or by behavior. We cannot really see the direct  result of an action potential--we see the secondary results, which may actually vary in timing in a visible way.
