It do what it do - ghetto axiom
The nervous system has two parts - voluntary and involuntary...wanna guess which one runs breathing and heartbeat? It's NOT the one Homer uses to scratch his ***.
these are involuntary bodily functions...they're the antithisis of deep and thorough ponderance......
Regularly,.......and In and OUT!!
My heart beats because of love, because of joy, because of anger, and pain, because I am a part of the universe. I breathe for all of those reasons. I breathe because I'm alive.
Heart - fast
Breath - slow
