Yes. And no, you don't un-age traveling inverted. You still experience aging and the progression of time, you're just inverted compared to the rest of the world. As far as we know you can only travel forward (normal time) and backwards at the same pace (it takes an hour of your time to travel backward one hour).
Which is why, like I said before, I don't think Neil can be Kat's son. He would have had to spend 15+ years inverted after he grew up, got his PhD, trained, and had adventures with the an older version of the protagonist.
Hmm, that causes problems though. Neil indicates (claims?) he has known Washington for years. But for that to be true, and for Washington to have just met him, that would mean Neil would have to be from "years" in the future. Which would mean, he had to invert for years, which would mean he would age those years. The more I think about it, the more this movie is simply a total mess which makes no sense.
