Part of my current lifestyle hack is walking. We bought a treadmill last year and since early this spring I’ve been walking 5 or 6 days a week on it. I’ve been using Star Trek: The Next Generation episodes as entertainment while I walk. Each episode is 45 minutes long and there are 178 episodes total. At a walking pace of 3 miles per hour I get 2.25 miles in for each episode. I’m almost through season 5 now. By the time I finish the series I’ll have 400 miles accumulated.
Of course then I’ll have to start Deep Space Nine, followed by Voyager and then Enterprise.
