Initially you said:
Maybe as botanists we should adopt the biological 10 day "week".
Howard Clase

What about plants?

How was this determined? Maybe it's just the way I was brought up, but I
remember being told about attempts in the past to go to a 10-day week, and oxen
dying because of not getting every seventh day off. Of course, they never told
me the source. I would like to know about actual research indicating a
biological week.
