Okay, kids, parents, teachers, advisers, counselors, professors.
Please do this to anyone that you think may even be remotely interested in studying history at the college and/or graduate level:
Have them lift a 14 gallon Rubbermaid container full of hardcover books.
Tell them they will need to do this many times whenever they move.
I don't want to discourage people, just let them know what they're in for.
