The 8 hour day we know now was not always standard. Apparently, people once worked longer days, and eventually legal and social change allowed the day to scoot from 10 to 8 hours. Sometimes when I work, I stay later when I wish to, and sometimes I leave early.. The flexibility works well, although I do try to err on the side of spending more time at work. I wonder if, in 50 years, people might work 6 or 7 hour days. More importantly, I wonder if perhaps the lunch hour will grow, instead of the ends moving inward. Imagine life with an hour spent enjoying life in a garden or by a river, right after an hour lunch every day. A pleasant jog, a nice conversation, a short nap. Makes me smile.
