The gradients, the change in curvature between one point and another, are too
large. If there's a tidal difference of 100 gravities between head and toe,
you'll be ripped into shreds - and the tidal forces are very much larger than that.

When you stick your hand in the shower to test the temperature, the sensors
for your hand *only* acclimate. Soon it seems perfect, but when the rest of
you steps in, it feels just like it did when you first stuck your hand in. To
avoid this, stick your hand in only for a few moments, and test it with your
*other* hand before entering.
