This has been posted about three time in the last 10 days. Did you search for it? The errors in it have been pointed out in all these posts. This is sort of useless. In general when you get a chain email you can be pretty sure its already been posted to FR.
Actually, I posted this, yes I did search for it, I didn't find it, so here it is yet again.
There are thousands of articles posted in FR weekly, I miss some of them once in a while.
