I was on a flight the other day (B-747) when an oxygen mask dropped by
accident in the business class cabin.  I was horrified to see that the
plastic tubing that connects the mask to the oxygen supply was
brownish-colored due to age.  I have an aquarium at home, and I know how
long it takes for air-tubing to turn brown.  While it is quite conceivable
that they use a higher grade of tubing in aircraft, that is not awfully
reassuring, because low-grade or high-grade, old tubing is old tubing.  I
shudder to think what condition the rest of the system is in.
