endorphine high is really addictive just as any strong drugs. Once you get into this mode, you can't sit around and DO NOTHING...

And yes we march to a different drummer than a couch potato (someone who prefers to lead a very sedentary lifestyle).

My younger sister is a marathon runner (almost qualified for Boston missed it by mere 2 minutes or so). She goes bonkers if she doesn't go out and run a fun 20 mile loop. And she does belong to a running club. I hate to run. I much prefer biking.

My parents think its really stupid to exercise. So they lead a very sedentary lifestyle. They think both my sister and I are out of our minds. I think my sis is out of her mind too 20 mile fun run??

So yes we are different.
