Frankenstein author Mary Shelley kept her dead husband’s heart and carried it with her for almost 30 years until she died in 1851. It was found in a desk drawer a year later, wrapped in a copy of one of his final poems. Source
Death here in the physical realm. We must realize at some point in life we are super spiritual beings walking around in flesh, bone and blood avatars and we return where we came from at what I truely believe is a pre ordained or appointed time. We return where we really belong. Many people will disagree or never understand this.
