Lipstick & Make-Up
so at least you'll look pretty, whilst your looking at yourself in the indestructable platter and wondering WTF did I lug this hard-drive all around the place for ????
and yeah, I'm taking the piss, but your idea is actually, in it's essence, how survival is won (And part of the whole idea of the thread that you initiated I suppose).
To be succinct - to increase chances of survival, "one" needs to be able to SEE & UTILISE anything and everything at hand, often for a purpose that in no way fits the original utility.
But really, re: "platters".... in a real survival sense there are very much many more quite simpler and more abundant things able to be used for the mere reflection of light.
edit- sorry. My post of unusual survival item.....
A sense of humour and appreciation of irony.
(Morale, confidence (knowledge), WILL. The most important attributes)
think what you want. you are wrong.
The church says the earth is flat, but I know that it is round, for I have seen the shadow on the moon, and I have more faith in a shadow than in the church.
