Feeling deep affection, faith and trust can give life new meaning. The next time you're reluctant to take an emotional gamble, look at a small child and reconsider. For children, unconditional love comes naturally. For adults, it takes some effort. When loving unconditionally works, though, it's the greatest feeling in the world. People in committed relationships live longer. They also report being happier and more fulfilled. Love can seem like an unrewarding obstacle course sometimes, but making it through to the other side has big benefits.
