The number of possible thoughts is determined by calculating 
every possible pattern of brain activity.
   
  neuron = smallest decision unit
  neurological pattern = collective condition of neurons in the brain
  thought = collective condition of neurons
  possible conditions of a single neuron: firing or not firing = v = 2
  number of neurons in brain = c = 100000000000
  e = v^c
every-thought = e = 2^100000000000 possible thoughts
 
  rate of thought during waking hours (10 per second) = 36000 thoughts per hour
  rate of thought during sleeping hours = 3600 thoughts per hour
  number of thoughts per day = 604800 thoughts per day
  average number of thoughts per lifetime = 114847771860000000 thoughts
percentage of possible thoughts experienced over lifetime
  = 100 x 114847771860000000 / (2^100000000000)%
