Fears, assumptions, guesses, etc.
  1. Once you buy a house it is yours and done immediately.
    No mortgage, no payments. I just assumed everyone wrote 1 big fat check, always.
  2. Algebra is essential to daily life
    Uh oh!
  3. Driving a car is as difficult as in Cruisin' USA
    Those car arcade games? HARD not to crash into a wall. I was terrified.
  4. Everyone gets married and has babies by 25
  5. Clearer understanding of stocks
    Also general math and basic human interaction
