What was different about today?

At the end of class I was so much more tired and stressed then yesterday. I think that in factories the work has to be done twice as hard that when it was just cottage industries. Also for mass production the "gangsta" bear was very hard to mass produce. Also yesterday we had more time to make one then we had time to make alot more. I calculated the number of bears per minute and it was 1.5384615384615384615384615384615. And the bears per person were 3.9. that was surprising because it took 40 minutes to make 1 last time.
