18SX - U've been warned

Here I am, to post something new, which I find its quite interesting. It happened right after my lunch, where me and my colleagues walking around in a book store. The cover's magazine caught my attention with a very interesting topic (refer to pic) :-

Interesting topic

Guys or girls out there. Can help me with this? I thought of a few, but.. yea.. its not appropriate to post it here. Put in the comments box is a better idea though. :-)
