Hi i'm 44 years old,currently unemployed,i live near Peterborough in the UK. I got interested in prime numbers through the online ARG Perplex City,(trying to find out if the Reiman Theory could be proved). Unfortunatly its one of the millenium questions still left to be answered(but with a prize of $1million i'm sure someone will try soon).
