Heart, internal clock, a faithful companion of human life, and when the heart stops, when you end someone's life, we feel Woe a sudden, sharp nostalgia for what is gone, and if returned, would never be the same. The watch is a faithful companion of life cycles of humanity, and when they stop, we are imbued with a sense of loss. This means that something has gone before us. Of course, will come something new, but that we will not repeat.
