The Living Centrifuge

Apparently, endorphins are received by the brain in the same way that opiates are. Perhaps the fact that I haven't really danced in three days has something to do with the low mood. Apparently intense physical activity increases endorphin production and uptake. I'm not saying that it is the only reason, but might be a contributing factor. It's nice to know that chemicals in my body might have something to do with it, and that the chemicals might not be causing bipolar disorder.
