For me SRK is legened and related to performance what he can do, no one can even touch.
I like his personality always look good and presentation in movies no one can pretend he is 50+ .
He is single women man GAURI Khan that enhance his popularity by being one women man. Aprt from it he is good son/husband/father/business man.
SRK is popular by his romantic persona on accross the globe.
I wish he live long, I always admire his acting.
