Reader James writes in and shows how he keeps his place while reading on a treadmill. Most treadmills have a spot to hold your book, the problem is there is no way to keep the book from slamming shut without holding it. James explains that you can cut a bicycle inner tube (costs less than $5.00) in half and tie it around the treadmill. It appears that you would need to move the inner tube every minute or two when you get to the spot on the page that the tire is covering up. Regardless, this seems like a really handy way to keep your place. Do you have any suggestions on how to improve this idea? Please let us know in the comments. Thanks, James!
