Well, getting back to brass tacks, how in the heckfire could the bridge support Hurley and not Charlie? That's one that boggles the mind, unless it took a while for a rope to become totally unfrayed.
Didnt that guys wife who was in the navy say that her husband felt that the numbers brought bad luck to those around him and not him...ie:she lost a leg in the car accident he walked away from(head on collison with a semi truck)
So I would say that the numbers bring good luck to those who use them and bad luck to those around the user
