It's hard to remember, but once upon a time, women put on makeup BEFORE they left the house.  Ask the milkman or read about it in the evening paper.

Those days are OVER.  According to a new study, 67% of women say they put their makeup on during their morning commute on public transportation.

And 75% of those women say something has gone wrong when they do it . . . usually from a sudden stop.

For that reason, eyeliner is the least-common thing women put on during their commutes.  Lipstick is the most common.
