Maths genius Grigori Perelman - who's already turned down the Fields Medal - is now saying no to a $1-million prize. (This after he cracked the Poincaré Conjecture.)
"I have all I want," he said, shunning a life of fame, fortune and maths groupies in favour of a simpler, quieter life. For wannabe recluses and aspiring hermits like myself, this man is a total hero.
