please help me with three ideas/sentences. Why metal is important?

1. Well, if you make a kettle out of metal you can boil water. If you made it out of plastic then the kettle would have insufficient mettle to handle the heat and you'd end up with water everywhere.

2. Without Metal we'd probably still be listening to The Seekers, or The Weavers, or *gasp* Bing Crosby.

3. And if there were no metal in the world there would be no gold so that Forth Knox would have to be used for storing cookies instead of the US gold reserves. And that's just as it should be, because if they were to store gold in wooden vaults (no steel to build strong rooms) every bad guy and his floozie would just wander in and help themselves.

On the other hand it would be all bad. After all, if there were no metal there'd be no guns, and the NRA would have to focus on archery. I can hear their slogan now: "Arrows don't kill people; people kill people."
