Pei Yu - one of my spam friends - writes with a riddle.
"What 'magic pill' can help you shed 15 pounds... turn you into a real estate tycoon... help you read faster... make you a better lover... and help you amass a personal fortune? Come on detective. You should know this one!"
Sherlock Woodford is still working on this one Pei, me old mucker. And I don't want to spoil the fun by clicking on your link to find out more.
I'm sure there must be a clue in Pei's unlikely job title, which is 'Success University Independent Distributor'.
