The nurse in this building says it's likely the absolutely massive amount of salt I consumed the night before without any physical activity to induce sweating. When I sweat, it's like the Dead Sea; that fluid is corrosive and acrid. I should have done some stuff on the Wii Fit or played Punch-Out or something, or biked out to my parents' house but it was a little late for that ... any of that stuff gets water moving through my body and out every orifice it can find an exit through, carrying tons of salt with it.

Of course, the nurse also tries to tell me that sudden temperature changes--both the weather fluctuating between 85F degrees one day and 101F degrees the next and the sudden temperature change from 70F indoors to 90F outside just minutes before I begin my bike ride home or to work--makes it much more difficult for me to bike because my body has trouble adjusting to the weather/temperature changes. Apparently pre-industrial-revolution Arabs living in open stone buildings without air conditioning have it easier than modern American, European, and Asian societies living in high-tech housing, because it's easier to deal with constant desert temperature than with fluctuating AC inside and ungodly heat outside... right, okay, sure.

Oh well, there's something I need to retrieve from 9 miles away from my house tonight, so I'll be trying to do an 18 mile trip in under an hour and a half. That should clear everything out. Guess I should take a couple liters of water for that trip, too.
