The Inevitable Disintegration of Devices

Devices and object continue to deteriorate.
my laptop is incredibly slow (again), an aching crawl from Facebook to Bridge 39.
My glasses get worse. The scratches on both lenses turning the world into a kind of carnivorous fog that seems to eat things up.
My i-pod stops playing ten or eleven times on each song it plays, necessitating having to hold the thing continually so I can press play again. A constant interruption in the flow of the songs...
When I turn on the television there are rather alarming cracking noises coming from somewhere inside the structure.
The DVD player makes annoying groaning and whirring noises during the playing of a disc.
Devices break down of course, but why are they all happening at once?
