> Its like driving your car 3 blocks instead of walking, your physical health will suffer.

And be sure to only walk barefoot. Relying on artificial shoes weakens the muscles and the skin of your feet.

A reasonable compromise in the face of frostbite and hookworm.

I suppose critical thinking skills are also as bad, making you question the state of the world. Problem solving is another one, deluding one into believing there are solutions to suffering.
