At this event, getting physical can help you save a life—not create one. The Emerson College Police Department is offering a class to teach participants how to “respond in a cardiac and breathing emergency,” as Emerson’s website says, by performing CPR and using an automated external defibrillator. 

They’re skills that take just four hours to learn but may last a lifetime. The course is accredited by the American Red Cross, which requires a $19 fee—less than a week’s worth of lattes from Starbucks—for processing certification cards. The Emerson website notes the course will be canceled if there are fewer than 10 participants, so be sure to RSVP by today for a real heart-to-heart on Sunday.
