When I was..younger, me and a buddy spent all day trying to break some of his old toddler toys. In-frikkin'-destructible. Not so anymore. Everything's built to need replacing -- the key is to figure out the sweet spot of how long to make them capable of lasting.. long enough to have a decent reputation, but not so long that they can be used for the life of the owner or handed down from generation to generation, making further production (and thus the company) pointless. Similar might be said of board certification, come to think of it. Just wait, by the time I retire the recertification cycle will be down to a couple years, like phone upgrades.
