A lot of moms who are not working because they are well provided for by their husbands easily get bored.
Aside from taking care of the kids and looking pretty, they long for something to do. A good activity is to venture into baking. It could become a business where you have those big ovens already, but if not, it is really a nice endeavor that will make your family happy.
In another light, I really wonder about those big lab ovens that are often seen in those science channels. What are the things often cooked there? These are big and can be very hot, so that means they can melt even metal, right? Oh well, that is not something that I see everyday.
