What are peoples' opinion on preventative maintenance?

"If I'm at home and just doing local trips, I'll wait til it dies!
Something that can cause catastrophic failure, you bet, nip that puppy in the bud, but I'm not one to just replace expensive stuff like climbing a mountain, because it's there."

Well said.
