If you were falling feet first into a black hole you would be crushed in the
left right, and front back direction as I've described because spacetime
would have a positive curvature in those dimensions, like a sphere, so two
geodesic lines would converge. Things are different in the up down direction,
spacetime would have a negative curvature in that dimension, like the inside
of a bowl or a saddle, so two geodesic lines would diverge. You would be
stretched in the up down direction and crushed in the right left and front
back direction, an interesting way to die.
