In the Fall of 2010, we had many Alside window sets put in. When Spring came, we opened all but four of the windows 1/4 to 1/2 way. We never fully closed and locked the windows until late July/early August when the hurricane was due to come up the east coast.
Almost everybody in the Iron Age was involved in farm work and that goes for women and children, too. In order to prepare the land people used a special kind of plough, an ard, which was pulled by a couple of oxen. That was probably the men's part of the work. Very few people were actual artisans.
However, since we're talking about the Iron Age as a historical epoch, more caution and elaboration is needed. The short answer is that Iron Age generally refers to a particular culture's stage of development and, by extension, commerce. As such, historians generally don't use the term in very often because it does not refer to any standard bookend dates of when it ended.
