Narrator: HOW MUCH G-FORCE CAN I HANDLE??
T-Rex: A regular person in regular person clothes can handle about 5 G before they pass out. Not bad, regular person!!

T-Rex: But what's that? You want MORE acceleration? MORE of these delectable forces of G??

T-Rex: Okay! We'll get you a flight suit: that'll push your limit up to 9 G. Wait - still not good enough? Well, we COULD submerge you in a liquid that has the same density as your body.
Dromiceiomimus: This distributes the G-force all over your body rather than on a single spot, making you much more resilient to sudden starts and stops!

Utahraptor: What does that get us?
T-Rex: 15 G.
T-Rex: 20 G, tops.

T-Rex: But you STILL want to go higher? No problem! So you've got these hollow weak points inside you called "lungs". We'll be filling those AND EVERY OTHER BODY CAVITY YOU'VE GOT with the same liquid you're immersed in. Tada!
Utahraptor: Wait. Do we know WHY the person reading this wants to handle 20+ G?

T-Rex: Utahraptor, PLEASE: whatever's going on here, we're clearly at the level where it's gonna make the news if it goes well OR catastrophically wrong.
T-Rex: Personally I'm hoping for a little of both??
