I have spent so much time staring at video footage while tweaking de-interlacers I can often see 
interlacing artefacts and jittery movement where a "normal" person can't, but only on video screens 
and not in the real world ;p)

Along the lines of what you are saying, I have spent so much time listening to and studying lossy 
compressed music I can often hear artifacts where in fact there are none. I'm beginning to fear some 
form of programmed hearing damage (Not physical but psycholgical). Having said that I can pick an 
mp3 at 100 paces with one hand tied behind my back. Perhaps my hearing has becomed super attuned to 
phase variations and other colouring of sounds that normally we don't process.

I am worried that continued exposure to lossy compression (video and audio) has the potential to 
alter the way our brains process sensory information as we become optimised to processing this kind 
of input.
