So it turns out we've been wrong about this whole "manspreading" thing. It's not a rudeness issue, or disrespect for other people's space. Manspreaditis is an embarrassing physical condition inflicted on a surprisingly large percentage of the male population. The below video, produced by Mark Malkoff, is meant to serve as a tool to better educate an insensitive public about this common but largely undiscussed affliction.

Manspreaditis is not curable, but it is treatable. Doctors advise sufferers to avoid the subway, and recommend instead commuting by bicycle or on foot. If the condition is particularly severe, treatment plans may include just staying home altogether.
