Well, i for one am convinced that all these celebrity Deaths; Bowie, Houston, Prince, Cornell, Ledger, Murphy, Williams, George Michael, Philip Seymour Hoffman and so on are not really Deaths but them going down under in their bunkers. They are in the know and aware of that the shit's about to hit the fan and that there's too much pollution and poison already up here so they're going down in their bunkers to live until it hits.
Now these bukers are very expensive and filled with luxury, in fact they've built whole towns down there and so it's better to live down there than up here amongst the rest of the "poor people". Check out the bunkers and you'll see what kind of luxury they have. So it's temtping to fake your death in order to dissapear. We're talking state of the art ventilation, your own pool, stores, perfect roads and speedy transportation.
This IS, after all, the Power elite with Money like grass. They only accept the best.
