Feeling "free", why and how?

To feel “free” – is a special sensation, that is a class all of its own.

How, and why do we feel free?

Does a caged, wild animal feel free?

I’ve theorized that to feel “free” – is actually the sense of an organism when it is closest to its most natural state. To experience true freedom, one must experience his most natural state of being. This includes a freedom from worries, good-health, satisfaction of need, strength, awareness, and a general absense of opression.

Any comments?
