Lost pounds

Seems like some of my friends have already kena-ed the lose x amount of pounds aka lose weights adware or spyware or virus or something like that.
From my knowledge, a computer will only get infected if the victim clicked on that link. So is it really curiosity? Or obsession to lose weight aka be perfect in this materialistic commercialised world which 'motivates' people to get attracted to these false promotions or deals and ended up causing them to get their computers infected with these problems.

Actually, I have a better way of letting people lose their pounds a whole lot faster.
Go to a money changer, change all of your savings from Singapore dollars to British pounds, then give it to me. In this way, you will lose your pounds.... to me!
