These little heart-shaped pillboxes hook unobtrusively to purse, belt, walker, buttonhole, golf bag, keychain -- dozens of items you use every day -- to keep your potentially life-saving aspirin close at hand and easily accessible. At the first sign of a heart attack, medical advice is to first call 911 and then chew and swallow an aspirin. The pod is big enough to hold the exact recommended dosage for heart emergencies: Either four chewable 81mg tablets, four 81mg coated baby aspirin, or one adult aspirin.
