I got this email today and its very important for you ALL to read!!

A word to the wise.
>
> PIN NUMBER REVERSAL (GOOD TO KNOW)
>
> If you should ever be forced by a robber to withdraw money from an ATM
> machine, you can notify the police by entering your Pin # in reverse.
>
> For example if your pin number is 1234 then you would put in 4321.
>
> The ATM recognizes that your pin number is backwards from the ATM card
> you placed in the machine.
>
> The machine will still give you the moneyyou requested, but unknown to
> the robber, the police will be immediately dispatched to help you.
>
> This information was recently broadcast on CTV and it states that it
> is seldom used because people don't know it exists.
>
> I checked with my Bank of Nova Scotia to see if this was correct and
> staff said yes this information is correct.

> Please pass this along to everyone possible.
