Could Boolean logic and Venn diagrams be useful in everyday life? How might they be used?

When faced with a maze of complex information, many people make an outline that organizes the material and makes it easier to understand. Whether we are conscious of it or not, most of us are constantly organizing and analyzing information. Driving to work, shopping at the supermarket, and registering for courses at school all involve decisions.
For example, we might seek a driving route that takes us past the bank, but avoids a busy intersection. Or we might look for a store item that is on our shopping list, is on sale, and is in stock. Perhaps we have to find elective courses at school that meet certain criteria, are offered this term, but are not outside the area of our major.
In each of these cases, instead of an outline, we could use Boolean logic and Venn diagrams to represent the choices and alternatives. Students might try these examples or others and then discuss the results.
