While I'd agree with you 'in the wild' on a random person, if you watch Neil for a length of time on stage,.... he has an energy about him. It almost exudes as a hyperactive type of quality. Not many people are excited about space "stuff" - so I can see him just becoming overly excited when people ARE interested.

I've watched NDT quite a bit (being an amateur astronomer myself), but that statement is still creepy. I don't think that being 'energetic' automatically excempts any individual from criticism for their actions and words.
