back in the early 80’s I wrote 400kLoC in the course of a summer (APL/360, very short lines), printed it all out on green bar fanfold paper. Stashed the printouts in binders on bookshelves, the shelves collapsed and I got nasty bumps and paper cuts. If you meant conceptual injury, I try not to dwell on it, but I once wrote a makefile that “clean”-ed up all the source code, source control, and the backups...just a cut and paste error, but soured my original exuberance about make. For life.
