The efficiency expert concluded his factory lecture with a warning: Dont try these task-organizing tips at home.

Why not? asked a worker.

I did a study of my wifes routine fixing breakfast, explained the lecturer.

She made a lot of trips between the refrigerator, stove, table, and cupboards, often carrying only one item. Hon, I suggested, why dont you try carrying several things at once?

Did it save time?

Actually, yes. It used to take her 20 minutes to get breakfast. Now I do it in seven.
