Assume that you live in the 19th Century and are spending your day spinning yarn.You have already washed the loose wool several times and carded and combed it. You spin the wool into yarn from daylight until dusk and neglect your usual activities such as cooking meals, tending children, working the garden, milking the cow, chopping wood and hauling water.
How many days would it take to spin enough yarn to make one pair of men's socks?
(The answer is approximately three days...more info in the comments section.)
