Hi Maureen,
I like the way you think. We do need to laugh. Laughter helps to get the blood flowing, the brain cells firing and our bodies flexible. Once all this is done learning can begin. By starting at such an early hour if you didn't use humor in the classroom I'm not sure how you would get them started. I was raised on a dairy farm so my days started at 4:00am, 7 days a week. Maybe that is why I'm not a dairy farmer today and that I teach classes beginning at 4:00 pm and ending at 10.
