Do take what I say with a grain of salt, but my late night napkin math says that (assuming a now rectangular human that’s 16 inches wide and 72 inches tall) a person should have a frontal surface area of 1100 inches, under 6000psi, that’d be about 6,800,000 pounds of pressure on them - instant death.

These are styrofoam cups that’ve been crushed by the pressure at the bottom of the ocean. The water isn’t looking for your nose, it’d just crush your outsides into your insides until you hit a relative density, like the cup, but not as pretty. The air in your lungs would instantly compress and heat to several thousand degrees C, turning your insides back into your outsides. I think.
