Natural Selection Seems Insufficient

[Jal]

Looks like we have to add "reflexes" to the INCONCEIVABLY long list of things someone is ignorant of.

That's how hunger works?  Reflexes like - a knee jerk from a rubber mallet? 

Ok let me get this straight. I'm just a domino. A passive observer. At the moment of hunger, the universe just so HAPPENS to intervene.  (Oh lucky me!). It issues me a series of knee-jerk stimuli, and I can no more halt these effects than I can keep my leg steady from the rubber mallet.

This series of knee-jerk stimuli cause me to INVOLUNTARILY do the following:
- I don some attire.
- I grab my wallet and my keys
- I enter the car and drive to the grocery store
- I purchase the list of items in my favorite recipe.
- I come back home and cook it, and eat it.

 And since I'm just a passive domino, I'm just as SURPRISED by each of these activities as I am by a sudden knee jerk. I had no control, I couldn't have stopped the process if I wanted to. Each activity was a deterministic push/ impetus outside of my control.

That's how it works, huh? Ok. Got it.
