Take the last two digits of the year you were born plus the age you will be this year, it will equal 111......
Not really spectacular. You're counting from a common point (1900). It is now 111 years after 1900. The year you were born (say 67) plus you age (the number of years since you were born...44 in this case) will equal 111.
Look at is this way. The FULL year you were born (1967) plus you age (44) equals Current Year (2011), as that's how we count. The only thing that's different is that THIS year, if you subtract the 1900, you get three 1's.
Next year, the same calculation will equal 112 (current year - 1900). Suprisingly (not at all) the year of your birth plus your age will alway equal Current Year - 1900 (unless, of course, you were born after 2000, in which case Age plus Year born = Current year - 2000).
And, btw...the new millennia actually started in 1/1/2001. :biggrin:
