Izumi Arai of Tokyo has solved the problem of death. Naturally, he's applied for a patent:
Mind Personality Transfer Method (#US20020088467)
This invention can permanently in the future develop minds and personalities of creatures which were considered in the past to decay and become extinct owing to ageing and death, by transferring minds and personalities of creatures to new clone bodies, with preserving self-identity. This invention is particularly valid in the case that an invalid has little chance of recovery due to serious multiple organ failures, in the case that general prostration or severe senility of the whole body makes urgent organ exchanges ineffective, in the case that it will not be long before an individual moves to new clone bodies on some other grounds, etc. My invention is the repetitive processes of transferring central nervous systems and other systems of individuals and old clone bodies to new clone bodies.
Besides the process of transferring central nervous systems themselves to new clone bodies, ... by inputting memories retained in original individuals and clone bodies to central nervous systems of new clone bodies beforehand, creatures can obtain existence bases of themselves in succession, because memory itself can be regarded as the independent personality.
Combining freely a great many of organs such as central nervous systems, peripheral nervous systems, and other systems, can enlarge memory capacities. Moreover, by establishing new active pathways, the originality worth of oneself can be formed. Remaking gray matters into chips such as semiconductors, various integrated circuits, etc., makes nervous systems light and convenient. The information interchange between lots of brains beyond a tiny skull and the construction of new nervous systems can evolve central nervous systems as a whole.
Creatures can maintain self-identity even if constituent elements of succeeding creatures are different from those of preceding creatures, because creatures always exchange their constituent elements by respiration and metabolism.
Furthermore, the consciousness of oneself can maintain continuity in the case that the infant self is lasting to the adult self, in the case that a particular self can put on weight and can lose weight, and in the case that the organs of oneself were injured in diseases, accidents, etc., and the self gets one's health back again. Namely, creatures can transfer themselves in succession to new clone bodies continuously and spaciously, even if succeeding creatures have different shapes, sizes, functions, constituent elements, etc.
Therefore, with keeping self-continuity, I can create the existence of multi-arms and multi-legs, by making the most of lots of other systems in addition to nervous systems simultaneously. And, by obtaining various new organs, I can extend individual faculties of creatures diversely and remarkably.
Of course, you're now asking yourself: How will he perform mind transfers from a mature brain to a new one while avoiding self-discontinuity anxiety? Simple:
Putting both old and new brains into operation simultaneously and transferring functions gradually from old brains to new brains make it possible to realize self-continuity as time passes, without anxiety.
Fresh brains can be brought up, while coming into subsidiary operation, with carrying these immature brains on one's back.
You'll have a hunch with a hunch! While an exciting prospect, this will cause some inconveniences. Besides complicating AFDB construction, new chair designs will need to be developed to avoid back-brain injury...

Also, your shirts won't fit right. But considering you'll keep adding more limbs with every new body, you'd probably want to chuck them all and start wearing ponchos instead.
