going through the motions

In prison, they swab your arm with an alcohol pad before they lethally inject you.

~ George Carlin

Understand how silly that is.

It is easy to get so caught up in the motions of things that we fail to think through why we do much of anything. 

We do what we do because it's what we do, don't you?

How could a person who is about to be dead in less than 10-15 minutes develop an infection from the injection that is about to kill them?
