Follow the instructions as quickly as possible but do not carry on reading the following questions before you finish the previous one. You do not need to write the answers, just do it using your mind. You'll be overwhelmed by the result ... How much is: 15+6         3+56           89+2           12+53           75+26         25+52           63+32           I know! Calculations are hard but this is the real thing, folks! Come on, a few more ...           123+5           QUICK! THINK ABOUT A TOOL AND A COLOUR!         Scroll further to the bottom ...         A bit more ...           Just a little further ...         Have you just thought about a red hammer??? If this is not the case you are among 2% of the people who have a 'different' if not 'abnormal' mind. 98% of people would answer a 'red hammer' while doing this exercise. If you don't believe us, tell your mates to do it and you'll see. We have no idea why this is the case but you've got to admit, it's bloody cool isn't it. (That is unless you are one of the 2% who no doubt are thinking 'what a pile of shit'!)
