Mark McClusky says for elite athletes today, pushing boundaries and breaking records is all about "the aggregation of marginal gains."

As the summer winds down, universities are gearing up for their annual fall move-ins. But recent mass shootings, at a movie theater in Colorado and a Sikh temple in Wisconsin, have these schools thinking serious about security.
These very concerns inspired the head of Boston University’s police force to tweet about a detailed, some would say disturbing, security video to more then 1,200 Twitter followers. The video was produced by the Houston, Tex. Mayor’s Office with a grant from the Department of Homeland Security, and is meant as a survival guide in the event of an active shooter.
In the video, office workers face the onslaught of a gunman. Some characters die, but others use the movie narrator’s advice to stay alive: run, hide or fight.
