Maybe. *That's* something I look forward to. Self-organizing 3D
   simple nano parts. It'll be a fun progression. If they can
   supplement white blood cell activity, passing slowly through the
   lymphatic system, they can do a lot of good.

   Unfortunately, much of the lymph system is still a complete
   mystery compared to the blood for example. I expect to see
   nanobots accumulating under my armpits and having to massage
   them out when the weather gets bad
