Taking damage from being jumped on

When an entity falls on top of another entity, the entity that fell takes fall damage. However, the other entity is left completely unscathed, despite being practically squished.

What I propose is that if an entity falls on top of another entity, the damage is spread out among the two, so that the entity that fell takes 25% of the damage, and the entity that was fallen on takes 75%. The reason it is not the other way around is because that isn't how real life physics work. If a person fell from a house on top of someone, that person would still be hurt, but the one who they fell on would be worse off.

This could be an interesting mechanic to have in the game, and would be very useful in survival mode!
