Many aeons ago I read a short story in a SciFi anthology with the following plot, as I remember it:
A man ingests Nanobots [?] which travel though his body, fixing disease and repairing damages, etc. Then they start to take over, improving on his human biology --improving his senses & strength, etc. Eventually, they begin to expand outside his physical form, 'integrating' him into the fabric of his house -growing parts of him into the electrical and plumbing systems, etc.
Note the 'as I remember it' so this may be, at least partially, inaccurate. But, given the germ of the plot has stuck in my noggin all these years, I'd love to find that story and read it again.
Anyone recognise it?
