Well one should always look for new and exciting things by turning over rocks and seeing what scurries about. The funny thing is, that in looking for new and exciting things, you frequently run into information or ideas that can make your job easier. It also is a good way to take a break from a nettlesome problem and give your brain a chance to relax a second before you go back to working on it. Besides, all work and no excitment make for a grumpy Athelstanent :)
