Let me asphyxiate for fun!

Alright, so here a true musing by Obi:

During my bike ride to work today (which, I only mostly died as opposed to dying outright), I started thinkign about this growing sense of euphoria. I had been riding my bike, mostly uphill for the last 15 minutes, and started to feel my body become lighter. I was taken by a sense of everything being "just dandy".

As is typical of me, I started internalizing and observing what was going on to me. Euphoria! So this is what all the runners and cyclists tell me they feel when they do their cardio for awhile. Supposedly, it comes from some neurochemical release due to exercising in such a fashion. I'd like to put forth an alternative theory.

My theory: the sense of euphoria is experienced because the brain is oxygen deprived. Yes my friends - it's the equivalent to being in a room with too little air. After the panic of near deathness passes, you should start feelig like everything is just "dandy" - this is the equivalent of your brain being drunk.

Seriously - watching my heart rate monitor, my heart rate was racing. All the blood and the precious oxygen it was carrying was being sent straight away to my heart and legs. My brain was a secondary thing to biking - after all, it's just sitting there, floating contently. My heart and legs were like "screw you brain! We're dragging your fat lazy ass with us. What are you doing? thinking?! WTF?! that's not getting us up this god damned hill!". Or something along those lines.

So yes, my brain was oxygen starved. Hence the euphoria. A quick google search for scientific papers seemed to imply the same thoughts that were swimming in my oxygen starved head. Wait... but I need oxygen to think clearly. Oh whatever - I'll go hold my breath for a while until everything is "just dandy".
