This is not about a revolving debt story, where the owner of a credit card or cards pays off each and continues into debt.
It's actually about using your credit card to rescue yourself from a bee or wasp sting.
Tony's Pest Control Gold Coast site has an interesting snippet on why a credit card is recommended in case of a bee or wasp sting.
Instead of reaching for the tweazers which risk squeezing the venom into the afflicted area - using the edge of a credit card can remove the sting safely.
If done correctly the stinger will catch onto the edge and gently lift out of your skin.
Most wasps are actually solitary, non-stinging varieties. Wasps according to National Geographic do more good for humans by reducing insect populations.
Many plants depend on Bees to polinate in order to reproduce.
