For whatever reason the 111 equation didn’t penetrate until a friend pointed it out last night. Add the last two digits of your birth year plus your age this year (i.e., after your birthday) and the answer will always be 111. No exceptions. George Clooney, 50, was born in May 1961 — add 50 and 61. Scarlett Johansson, born on 11.22.84, will be 27 on her 2011 birthday — add 84 and 27. My son Dylan, born on 11.16.89, will turn 22 on 11.16.11 — add 89 and 22. If Jayne Mansfield, born on 4.19.33, hadn’t died at age 34 on 6.29.67 she’d be 78 today — add 78 and 33. Cary Grant, born in 1904, would be 107 if he hadn’t died in ’86 — add 107 and 4.
