To become physically or mentally addicted to riding bikes? Due to college and work, I had not ridden my bike in over two weeks, and every day that went by it seemed like I became angrier, moodier, less social, and easier to [censored], to the point where my friends had become concerned and pointed out the change. Didn't feel like ever doing anything, and did nothing but complain about just about everything, and snapped at very close friends a number of times. Yesterday I finally got out for a nice 40 mile ride, and voila, it seems I'm back to my normal, happy self. So is it probable, or even possible for one to become physically and/or mentally dependent on riding bikes?
Note: I've been riding all kinds of bikes, at least 5-6 days a week since I was probably around 10 years old. This is the first time I've really had something like this happen where I just didn't have time to do some sort of pedaling.
