How much usage can a LEGO piece take before it loses its 'clutch power'? In this article it's mentioned that one very important feature of the LEGO bricks are their 'clutch power' which is "the ability of its bricks to snap together tightly while also being easy to separate, thereby readily allowing for de- and reconstruction"

Since a LEGO brick is ABS plastic and will wear with use, I wonder how many times you can assemble and dis-assemble two pieces before they no longer stay together.
