Are you launching a space probe or just mucking about with PICs on the workbench? There's a spectrum of tolerable risk. All in all, PICs are pretty rugged, at least as idiot-proof as most of the other chips you might be using. But they're not indestructible. If you shuffle across the rug and pick up your circuit board, all bets are off. A wrist strap, properly used, can help a lot. The best defense is understanding how ESD is generated and controlled.
