Age is one process no one can overcome. Sooner or later, the reflexes start slowing down, the adrenalin may not flow like the younger days and the old enthusiasm for the game may be lacking.
But it is a tribute to Tendulkar that after 20 years of international cricket he is still as keen on the game as he was in November 1989 when the whole remarkable saga began.
And despite several fitness problems, he is far from frustrated. Indeed, he can always be galvanized into action for the big occasion.
