Lemme see...all of you guys who insist you'll be safe on your farms..how you going to time your gaurd watch rotations without a watch?
I think I would take an alarm clock first . If I wanted to be hunting before dawn, I don't need to stay up all night, wake up 2 hrs early or oversleep.
Kids with fever, problem farm animals, it's nice to be able to sleep knowing you will be up in a few hours.
Similarly if I wake up I like to look at the clock to see if it's time to get up or go back to sleep. I don't like just laying in bed (alone at least)
As far as a watch, I tend to time tasks. If the field is half planted, I double the time to see when I will finish. Rarely is this critical, and it my be due to me being an engineer and allways thinking in precise terms. But often it does help. Ditto if you can head home for lunch when it is ready (hence the dinner bell.)
Cooking, canning, and tempering metals all require timing. Somewhat true for medicine, though it's probally more our obsession with recordkeeping.
