Then you should know the joke about the difference between an English actuary and a Russian actuary. The former tells you your life expectancy ie an age you might expect to die, whereas the latter gives you a date, time and place. I suspect I'm somewhat older than you, and faults are already accumulating and have been significantly so for 20 years or more. I can see how it may eventually become too tiresome to carry on if some of the breakage can't be fixed. But there are often compensations...
