I am on one now, and perhaps you are too, searching through riddles. Distance be damned; wherever signals may reach, feel free to call me.

I spend my life growing, just so someone can make me shorter.

Abandon nineteen to turn sweet into sweat.

I have a grid of ribs, but I have no spine. I breathe in the heat, but the chill is mine. I am always boiling under the hood, Keeping things cool like a good guard should. If I spring a leak, you’ll be stuck in the smoke, Because when I stop working, your engine’s a joke.

Often unreliable, depending on who you ask. Alzheimer's robs this from us, what a pain in the ass..
