hmmm.. bears can go live in the caves 
but i've always wondered... why is our definition of 'life' so
narrow?
as if only carbon-based and all that like us... i think the concept
that life needs stuff like solar power and all that went to hell
when we found abundant life in the ocean where smoking chimneys
with temperatures which will kill most life on earth teeming with
shrimp, crabs, tube worms and bacteria
