Some people buy sports cars. Some people quit their jobs and travel the world. Some people run -- or attempt to run -- marathons.
Midlife crises can strike anywhere between ages 37 and 50, making age 40 prime real estate for impulsive, and sometimes drastic, life changes.
Judd Apatow's new film, "This is 40," -- a "sort-of sequel" to "Knocked Up" -- follows a couple with two children to offer a comedic look at life and marriage when you've hit the big 4-0.
Watch the trailer for the film, which hits theaters this Christmas, and then tell us: is this what your marriage looked like after 40?
