Here's AN INTERESTING ARTICLE ON AN ARCHAEOLOGICAL FIND in Norway that proves our ancestors were smelting copper as early as the Middle Ages.  I'm sure it was some of our relatives who had a hand it that one.

Middle ages.  That makes me think.  In my middle ages I used to say I couldn't even remember what it felt like to be young anymore.  Now, sadly, I can't even remember what it felt like to be "middle age" anymore.

When your young you worry about getting to middle age.  Then, when you're middle age you worry about getting old.  When you're old, what's left to worry about?  "That's all, folks"!
