Krishan Chahal was fascinated by the art of memorizing at younger age. In his quest to experiment on the power of his brain he memorized the value of pi upto 43000 decimal places breaking his own Guinness world record of 33000 decimals. Apart from this, he holds other two records one of them being remembering the sequence of several decks of playing cards.

He says he was not the best as a kid but learning and experimenting on his brain led him to have exceptional brain power. His feats are acknowledged by Guinness Book of World Records, Limca Book of Records, Record Holders Republic, Open Record Book and Pi World Ranking.
