The ancient Greeks had four words for love. First, there's Philía, the affection that blossoms from friendship; then there's Storge, the kind you share for a grandparent, or a brother. Thirdly, there's Eros, the "uncontrollable urge" to express your love. But New York Life says that the fourth kind of love, Agápe, is different -- that it's the most admirable. Expressed through action, it takes courage, sacrifice and strength; it's caring for an aging parent, trusting a friend to cut your hair, or rushing your daughter out the door on a busy day. The insurance company says that for 175 years, it's been helping people act on their love, so that they can look back -- or ahead -- and say that they did good.
