Birdwatching

A coworker told me I should get into a more active sport than birdwatching, which is too sedentary.  He is older than me, and a runner.  Mmmm. His concept of birdwatching is interesting.  We spent two hours walking around the City of Lubbock Cemetery and did not sit down once.  Granted, birdwatching involved stop and start walking, and you are not covering distance, but you are on your feet. Not cardiac exercise, but good to do, anyway.
