Oscar and Grammy-winning Indian composer AR Rahman feels it is very important to keep reinventing. For that, he says, he keeps on challenging himself because after sometime the magic fades and the brain becomes numb.

"As humans, after a while, even the best thing becomes boring. In any event of life, that boredom is a human quality. The only way to fight it is reinvention, to do something," Rahman told IANS in an interview.
