Life expectancy of Interconnects & Speaker Cable?

In my oppinion (and others) cables will degrade over time. There will be oxidation over time, as no insulation is truely air tight (at least in the long run).
Also the more you move around with your cable, the more it will tend to "crack" between the crystals.
So what is average lifespan? According to VDH you should expect around 10 years.

Be honest - how many components do you still have in your setup that are more than 10 years old?
Anyway - assume 10 years for average cables, better ones could be double. In 10 years time or at least in 20, much better technology will exist, more vodoo or even new types of cables (HDMI and all the others that will follow).
If you have a "scrap" box, like I do, with old cables then try to take one that you used to use (but dont any longer) and try to listen. Did that with some old ones, and the sound was horrible..
