Answer :
Because the pressure in our body is pushing out so it cancels each other out so in space where little pressure our bodies will explode because it is unbalanced and the pressure in our body wants to hget out but the pressure outside is too little to stop also under the sea like 1000s of meters where the pressure is reeally extreme our bodies will be crushed because the pressure outside is far far greater then the pressure inside
It is important to know also that pressure is appliyed all over the body and cancels out since it results in a force applyied on each side of you.
