Great column, Rich, and I love the "Incan off sides attempt" by the Mayans with the Long Count.
Regarding your Social Security, you already missed the mark. Unless you are very long-lived, you will probably not live to collect the $80k to $100k you could have taken from age 62 to now. With full benefits, you have to get into your 90s to catch up, and that doesn't even account for the time-value of money. Ah well, enjoy your lunch on the 21st. I'm looking forward to the day and hoping for the best.
