This is creepy, Newt Gingrich Really Married His High School Math Teacher

[Red Arrow]

This fails the half-your-age plus 7 test, therefore it is officially creepy.

Only for 2 years since 21 and 28 works for "your" test.

LOL... too much math.  At my age, creepy factor becomes old enough to be my mother or young enough to be my daughter.  No division and addition needed.

Edited to add: I did your math and officially, some woman who is 1/2 my age plus 7 could be my daughter.  Blech!
