This is a letter to my next "self," and maybe to multiple "selves." I've assumed that I'll be cloned eventually, that my clone will be cloned, and so on. Because such iterations are like a scientific variation of reincarnation, it's only proper that I try to pass on the accumulated knowledge of a lifetime. It would be nice if you future Todds have some idea of what the first one learned, to give you a head start (you won't, needless to say, share my memories or live in an environment identical to mine). In particular, you deserve insight about the narrow-minded political forces that sought to prevent your very existence forces that may plague you in your own time. Not that there was ever any way they could stop cloning, short of bombing every laboratory on the planet.
