Immortality Inducer: It doesn’t look like much, an immortagen.

Most of the time, it looks like a pint of grayish fluid in a bag, a little saline, with a faint rainbow sheen. Intravenous tubing included. Responsible medical supervision not included.

But inject it into your veins – ah, then the magic happens. It splices, it lyses. It unwraps storage plasmids and writes then into your chromosomes, injects nanocytes into your cells, builds nanogenic artificial lymph glands to keep your system stocked with roaming nanocytes, and even tidies up your gross morphology a bit, especially if you were already old. (While you develop a high fever and a really nasty set of aches and pains for a week or two – the more so the more gross work it has to do. Don’t even ask what your excreta look like.)

And then you live forever.
