Riding a motorcycle makes you smarter?

This is a very interesting article. Motorcycling forces me into a higher degree of alertness, and it forces me to use a lot of different motor skills while simultaneously focusing on all those cage drivers on cell phones who seem to be unconsciously trying kill me. Strangely as well, while riding our reasonably straight midwestern highways, I seem to relax and also think about an incredible amount of topics and solutions to problems which are totally unrelated to the dangers of motorcycling.
