I didn't intend to be preachy either, thus the smiley. Because I bike a lot, I'll see your heart scan. (Insert another smiley here) Humane to animals is a good thing. I don't hunt, but I am a carnivore.
You may win the heart scan battle. Biking at about 18-20 mph is the best exercise one can do. My son is into competitive biking and he is in incredible shape with a resting heart rate we would all welcome.
