Its a question of size. The damage to cells is caused by formation of ice
crystals, which can be avoided if an organism is frozen quickly enough.
Unfortunately humans are too large to have all of their cells frozen
quickly enough to avoid this damage. Many smaller creatures have been
successfully revived after cryopreservation.
