Large mainframe Computers used to use a selectric typewriter for the output console so it typed fast for 1000's of hours. Late one night the yolk that holds the selectric ball broke. I used PC 7 to repair it and it typed for another 4 years before the computer was replaced. I can't imagine anything that took more strain than that yolk. But it never broke again.
