I'd just move the GPS to my bike and wire it up to a spare car battery. Then I'd have a good excuse not to work out ("But honey, if I go for a ride, it'll cost us...") AND I'd save money in taxes.

For what it's worth, Quicksilver was easily the driest of the three--it really felt like a history textbook, and I honestly don't blame anyone who gave up on the series (and possibly the author) after trying to make their way through it. I know it took me two tries, and even then it was a struggle. He started picking up steam with the second book though, and the third was quite excellent.
