The meaning is that if you a representative sample of 25 year-old
humans, and their ages remains at 25 years constantly during 800 years,
you should expect that half of the humans would have failed ater 800
years ;) Also in this case would be better to use Mean Time To Fail
instead of Mean Time Between Failures. The problem is that we usually
are only at 25 year age during a year (less if we have a 'failure')
