If ya ever watched "Hoarders", you will recognize the gathering cycle at the critical mass stage with old folks and their rusting crap hidden under grass, being ruined with each passing day and unwilling to sell anything. It's just plain crazy. By contrast, the folks that actually let go of dusty junk seem incredibly balanced and sane.
Wondering if the Picker show might be dangerous viewing to a budding hoarder. Would seeing all those hidden treasures increase a hoarder's compulsion to collect more? Yikes.
