As a child, I enjoyed taking things apart. Occasionally, I would put them back together in a different way. Once you reduce an item into pieces, the enjoyable part of the puzzle is to create new ideas, art or tools.
Imagine if we could take organs or skin or bones and reduce them down to the point of having puzzle pieces that could replace a broken arm, failing eye or damaged liver.
I wonder if starship doctors ever used the replicator in this manner?
