State of Being

I'm feeling a bit philosophic tonight. This has the potential to be a very odd post...but here goes. Let me see if I can phrase this question properly - have you ever felt that running felt more like your natural state of being than NOT running? In other words, once you start a run, your mind and body say "ah...normality once again!" Or, when you're walking around the house or in your yard, your body is dying to break into a jog, just because it seems more the norm than walking? To be honest, I've only had this sensation a few fleeting times. This could possibly go along with that "I feel like I could keep running forever" feeling. This I've also had in a fleeting and very rare instance. I've never really reached the level of fitness as a runner where I would know whether or not the "running as normality" affliction is possible. I like to hope that it is, since as a runner, this is a state of being I'd like to achieve one day.

Any thoughts?
