It was great to see Amitabh riding a scooter. One needs guts to re-learn to ride a scooter at that age. Hats off to him. However, I would have preferred if he had buckled the strap of the helmet. With celebrity not following simple rules, it send a wrong message.
He has passed the criticism stage. He need not care about what people are saying about him or his work. Everything about him is an open secret including his romance with Rekha during his hey days, hence he need not fear about anything including criticism. Criticism effects entry level and new and young actors.I am sure he would have also effected by criticism during his younger days. His advice is good though for young people working in any profession.
