A lot of times, when I fix something, I'll keep the old parts around until the new fix has proven itself. Too many times the new parts aren't quite right. I don't usually go back to the old parts, but use them to compare and assess what went wrong. After a month or so of good running I pitch the bad parts.

On a similar note, if my mother has food in the fridge that is a little bad, she won't throw it out or eat it. She puts it in the fridge until it is good and rotten, then throws it out with no guilt that she's tossing good food. Growing up during WW2 in France will do that to you. I think I picked up some of that mindset.
