Why Doesn't Iron Mans Suit Kill Him?

We have all seen Iron Man flying around at mach speeds, turning wildly fast and making turns that jet fighters can't even do.

Meanwhile his human body inside the armor does not experience the effects of annertia, gforces or impact at high speeds.

There must be some science behind it to back it up right?

Well, actually there is...

Nerdist, a youtube user popular for making videos about such said things, went into some great detail as to how this is "possible"

Tony's suit is an engineering marvel, and they explain many facets of the technology to help give legitimacy to the special powers, abilities and weapons it has.

I never read the Iron Man comics, but in the movie they really don't have a technological explanation for how he miraculously seems to be unaffected by crushing G-forces of sudden acceleration, the inertia of sudden stops and hair-pin turns, and especially the blunt force trauma from getting smashed in the face with Thor's hammer.

Certainly it appears the suit takes punishment, but Tony always remains unscatched, never a collapsed lung, broken bone or even a bloody nose.

In my infantile understanding of theoretical physics, the same technology that would be used to counter G-forces and sudden blunt force trauma to the body inside would be the very same technology used for Anti-Gravity which in my honest opinion would be a much more stunning technological achievement than his heralded Arc Reactor.

Was their ever an explanation proferred for this and if so was it indeed attributed to Anti-Gravity?
