I'm learning new definitions for stupidity.
Each night at work, I take my break out the back door of my restaurant workplace. The same area serves as a smoking place for patrons, so there is a prominent ash basin where I sit.
This next part applies to both human behavior and stupidity. The distance between the ash basin and the alley back of the restaurant is about 40 yards. During a 15 minute break, an average of three to four desperate people check that ashtray. About one in 20 find something. I presume these people check about 20 ashtrays behind restaurants to get a butt.
This gives me pause regarding the basic principles surrounding the sustaining of life by conserving energy. Screw the ill-health caused by smoking. These people haven't grasped the matter of surviving long enough to get cancer.
