As far as significance of 462, it has two meanings in this context. First, it represents me. 462 was my motorcycle racing number. Secondly, it is the theoretical idea of the next stage of human evolution. Right now, humans are composed off 44 and 2 chromosomes. Adding 2 more would make us 46 and 2, also known as, "Christ Consciousness". it is obviously not science, but I like the idea of humans obtaining a higher consciousness.
