The fall damage in the game is way too intense. I jumped and fell 2 feet and I broke my knees, rolled over and instantly died.  Any fall that has you travel fall 2 feet makes you bleed or kills you, less than 1 foot makes your screen go slightly red.

The fall damage itself is barely a problem, it's the damage increase from your horizontal momentum that does it. If you fall straight down with zero horizontal momentum, you can (barely) survive up to an 80m fall, but falling while sprinting can cut that down to anything over a 30m fall being fatal.

You can always turn off the fall damage if it bothers you too much. No shame in it.
