‘Dabangg’ star Salman Khan, who turned 47 today, said that now that he is old he has to work a lot harder than he did when he was young.

“Every fan appreciates me for what I did during Maine Pyar Kiya, but that work is different than today's work. In my initial films, I had lot of innocence. Now at 47, I am expected to do ten times better work than I did at 22,” said Salman Khan to a daily.

“The older you grow the better you have to look, the harder you have to work and action and romance should happen consequently,” he added.
