Answer:
It's been around for millions of years but is never more than a month old. What is it?
I'm at the head of an elephant and at the tail of a squirrel
What goes up but never comes down?
I look at you you look at me I raise my right you raise your left.
I can be thin but not fat; in your body but never on your placemat. I'm always better when I'm fresh but you'll never see me in the flesh.
It has no top or bottom, but it can hold flesh, bones, and blood all at the same time.
