Hibernating Dwarf Lemurs a Key to Deep Space Travel?

Maybe

Scientists have discovered that two tiny, clawless, tree-living lemur species hibernate. Underground. For up to six months a year. Given that the furry animals are primates, the findings have exciting implications for possible human hibernation.

From chipmunks to bats to even turtles, numerous wild species hibernate. By slowing their metabolism, breath rate and heart rate, these animals can put themselves into a state of suspended animation, allowing them to go without food or water (or bathroom breaks) for months on end.
