Well you might as well tell them about gambling (as long as you mention the negative side) because (and as they say) back to the subject, I would say a high percentage of adverts these days are for Bingo, Lotteries, Charity Lotteries, and Gambling Sites etc, it's impossible to miss them, always giving you ideas of what to do with your winnings, but funnily enough they NEVER mention losing, strange that.
