Waterbear and live forever.
Ummm...that would not be very fun...sure you can survive like -300 degree Farenheit(might be celsius i really do not remember) temps or greater but what kind of live is stasis? Besides they do not live forever. They live a very long time though...

As for cheetahs, man are you in for a surprise. Every single damned other predator steals the kills of and bullies the cheetah...Go watch animal llanet or Nat Geo. You'll see...besides they are almost entirely descended from a very shallow gene pool. They are the red necks of Africa! Fast(nascar) and inbred! Woohoo for stereotypes!!
