Shah Rukh, who turned 52 today, said no one is "invincible" in this world and even if the fame he has fades away soon, he will be happy with what he has achieved.

"I need to make sure that I do this with the belief that I have to keep doing this for the rest of my life. Otherwise, I can lose interest in it...
