I Like Numbers

So today I've been watching some DVR'ed back episodes of the History Channel series, United Stats of America and here are a few of the things I've learned today:

• When we multi-task, our IQ effectively drops 10 points
• 1 our of 7 Americans is tattooed
• The average single-family American home (as of 2010) is over 2300sq ft
• Money can buy happiness: it costs around $75k per year
• It is funny watching someone creep into a stranger's personal space
