It might be a bit long but it's definitely worth the read. I certainly recognized myself in some of the situations described. It is really difficult to remain awake when you're at the supermarket, waiting in line after a long day of work. Some people are, like mentioned in the speech, defaulting their behaviour to not being awake, and there's all kinds of reasons for that. Personally, I do everything I can to avoid tedious, boring, 'supermarket' situations like that exactly because I know it will numb my brain. Stay awake, people!
