How would a human survive a grenade?

If our body was composed of 100\% water with no hollow air-filled regions, such as our lungs, we would probably survive a grenade as the force from the explosion would be transferred through our bodies. Instead, when the explosion occurs, the shockwave compresses the air inside our bodies in a brutal manner,…

If you stood at the same range to an underwater explosion, the pressure wave would probably kill you [source: Landsberg].
