We call it “brain fog.” But, it has a scientific basis that us described as pre-syncope, hypovalemia, cerebral blood velocity, instability¬† or postural tachycardia. Or, if you fade out as the day goes on, experience periodic mental confusion, periodic rushed thoughts, etc.

Imagine writing an essay in each of these situations:

  • You just crossed the finish line in a marathon
  • You just lost 1/3 of your blood
  • You’re about to faint
  • You’re in the middle of the flu
  • You’re a passenger in an economy car driving down a cobblestone road
  • You’re in the process of running a marathon
  • You just finished running a marathon while having the flu, lost 1/3 of your blood, are riding in an economy car driving down a cobblestone street AND are about to faint.
