As I mentioned a few weeks ago, I've been a train commuter during the second half of this summer. First due to real construction in the basement; then due to reconstruction (and finally finishing?) the basement office. When I time it just right, the train and bike will take an hour each way. Commutes are a top driver of unhappiness, according to the social scientists, and it's not hard to see why: knowing you'll hand over two of your sixteen waking hours to repetitive travel isn't a good start to the day. While my train and bike are on the easier (and prettier) side of a Boston commute, I still end up, all those hours later, right where I started.
