Superstar Amitabh Bachchan has many fans and one can’t overlook the fact that at 67 years of age, Amitabh is still vigorous and raring to go!

No wonder, the GenX stars of the film industry look upto Big B for his sheer passion and determination to do everything he intends to do.

The lovely Minissha Lamba wrote to Big B on the social networking site commenting, “Dear Amitji, I'm in constant admiration of your energy. How do you manage to do so much in 24 hrs! Wish I cud learn from u!”

Sr. Bachchan is not just an inspiration but an institute in himself, what say guys?
