Bollywood Megastar Amitabh Bachchan turns 71 today.

The veteran actor said that he feels that years are going by quickly but feels that ageing was inevitable as well.

“It is 71 now. Just last year or just the other day it was 70! The years seem to pass by faster now than they did before,” Amitabh Bachchan wrote on his official blog srbachchan.tumblr.com.

There was a desire to push the pedal all along those early years, to mature, to become adult, to bring on greater age. Now, you depress the brakes pedal with equal effort, and hope to stem the slide as it were," he added.

The actor said that he has gracefully accepted the fact that he was ageing.

“No not I, I accept the years, the giving up on time, on age. It shall happen to us all. That is the commonality of the process of life. We are blessed, all of us," he posted.

The legendary actor who has worked in over 100 movies and is one of the most beloved actors worldwide and since morning Twitter has been buzzing with wishes for the actor from his fans and fellow actors.
