Think outside the box. Sometimes the little things can say a lot.
Really obvious ones like music (keeps me semi-sane), family and
friends, oxygen, neuronal synapses, food, mental stimulation, my
lungs, my aorta, etc. I could say the Appalachian Mountains just to
be different, but let's face it, I could probably live without the
Appalachian Mountains. Maybe.
I could probably also live without my big toe or something, but I
like it, so I'd prefer to keep it for now. On an aside-- I am told
I have very nice feet. It's a strange compliment, but I get it a
lot so I guess I should be flattered or something.
