When i think of heartbeats and lies, i think of a marriage. One man, one woman, every day, every minute, every second. Both hearts beating for eachother, in harmony. Good days pass, bad days last. The two hearts still beat for eachother. They race in the moments of triumph, and in moments of trial. Having children, raising them, knowing that they will someday take your place. Not wanting it to happen so fast. Eventually, those heartbeats grow fainter and fainter till at last they are hushed for good. Even then, 6 feet under, their heartbeats still beat for eachother.
