I'll never forget how my brother swelled up after getting bitten by a bee when he... and I ...were much younger.  Although I was much younger, it turned out my big brother was a big baby.  Or at least that's what I thought.  Later I found out he was allergic to bees.

In one of my health magazines I recall reading that if you ever get stung by a bee, apply a penny to the bite for 15 minutes. I guess the copper in the penny contradicts the bite.  Good information.

While I was working in the yard last week, I got stung by a hornet.  I knew I should have removed that hornet nest.  But right away, I taped a penny to my arm for 15 minutes.  I was amazed at how quick the penny took out the sting.  The next day I woke up, there was no sign of a bite.  Must be was not allergic to the sting.    

Good information and it didn't cost an arm and a leg.  Only a penny.
