Learning C and being able to switch freely between Decimal, Hexadecimal and Octal etc. have certainly affected things... I once joined in a game of Canasta with my parents and found that I kept making runs of 8, 9, jack... leaving out the 10. - I thought I must be going mad, until I realised my mind was now thnking in base 13 instead of base 10. Maybe I should invent a game of Binary Domainos or something!
