Do you think it's possible for a distributor rotor to last 223k miles?

Today, I did a tuneup on my car including plugs, wires, cap and rotor… I noticed that all the parts were Honda parts other than plugs. This is strange, because I bought the car from my brother, whom has owned it through most of the miles, and he would never spend the extra money on Honda parts. I can almost say with 100% confidence that he wouldn't ever by dealer parts because of the price and he's a cheap skate. So, do you think it's possible that these parts could survive this long? Keep in mind, the rotor was in such bad shape I can hardly believe the car could run… And it's running 1000x better after the tuneup.

Yes its possible for them to last this long, especially with the condition you describe them being in
