Yeah, it's not like LSD shows up on ANY drug test. He could just as easy not do it and say he did. Unless of course, he really likes that yearly trip. Which I highly recommend BTW.
That's why I phrased it the way I did, "resulting repairs". No amount of maintenance will prevent anything from breaking. But no maintenance greatly increases the likelihood of something failing because of that neglect.
Oh you said pain/hurt/sore/discomfort? Get the fuck out of my office pill-head!
