First one to guess correctly gets no award apart from imaginary ego points You are not allowed to attempt a prediction if you already know my exact age beforehand (this mostly applies to some friends) You cannot guess in ranges such as "11-19", specific numbers have to be used instead such as "43" You are not allowed to guess more than once in a 24 hour period, unless your previous guess would not be counted for breaking rules Guesses must be positive integers I will not announce who guessed correctly or incorrectly, until I conclude this experiment
