I found this on Facebook:
This year we will experience 4 unusual dates 1/1/11, 1/11/11, 11/1/11 and 11/11/11 NOW take the LAST 2 digits of the year u were born & add the age you will be this year it SHOULD be 11 or 111.
To which I replied:
It's not that mysterious. In 2000, your age and the year you were born added up to 100 right on the dot. Now it's 2011, which is 11 years later -- so it will add up to 100 plus 11. Very simple actually.
