As you’re going through your closet on Friday morning trying to decide what to wear, why not wear red? It is National Wear Red Day, afterall. The day is part of the American Heart Association’s “Go Red for Women” program, a campaign to increase awareness and lessen the risk of heart disease, the number one killer among women.

As you’re driving around town you might also see several buildings glowing red. For the next three days the Pacific Science Center, along with 200 other building across the country, will “Go Red” to stand in solidarity with women and the fight against heart disease.
