She would probably also outsource that mechanical work to a mechanic, just like you'd outsource the cooking work to the microwave/freezing company. Although, by outsourcing this work, you'd both have a little bit more free time. It might be a worthwhile experiment just to try for a month, if you can swing it.
You don't understand, I already do the shopping/cooking and the mechanic work. Outsourcing costs a lot of money. Plus, if the point of switching is to appreciate the labor of the other person, then outsourcing defeats the purpose. My point is, some tasks may not be equally suited for both people in the relationship.
Locating, finding, and managing interaction with appropriate help is labor, too.
And it's often a better way of getting the job done, even if the immediately obvious monetary cost is higher.
