Lung Fish, the fish that lives on land without any food or water (1)

A fish that can hibernate for years without food or water could help scientists one day figure out how to put people into suspended animation to buy extra time during life saving operations.
The African lungfish can sleep out of water for three to five years without any sustenance, only to wake up when freshwater surroundings become available.
A study showing what happens on the cellular level to the fish could help scientists one day induce a similar state in humans, making long distance space travel and more advanced forms of medicine possible.
