As part of the Generation Next season, the BBC has been asking famous figures for their thoughts about childhood - both their own and what they think of young people now.
Bachchan was voted 'star of the Millennium' in a BBC poll
Here, Bollywood film star Amitabh Bachchan gives his view.
What makes children different is their innocence and their utter belief in the simple things of life.
As you grow older, life becomes complicated, and children are so oblivious of this aspect of life. One always wishes that all of us could remain at that age and not be exposed to the vagaries of life, it would be such a wonderful world.
Obviously, one of the big changes from when I was growing up is to do with the whole communications system - the computerisation and the mobile phone and the easy access to information and the wiring up of the entire universe.
You have children of two years, three years, being able to work computers. We never dreamt of doing that until we were in our 40s and 50s.
Their easy access to a side of development and the ease with which they adopt and take over the functioning of these inventions is really quite remarkable.
When I was a child, two assassinations unfortunately left a deep imprint on my mind.
I was five years old when Mahatma Ghandi was killed, and his ashes were brought to my city, Allahabad.
And I remember the assassination of Indira Ghandi, who was a close family friend.
The best piece of advice I received was something that I learnt from my father: If things happen the way you want it, that's good. If things do not happen the way you want it, it's even better, because they happen through the will of God and he would not want to do anything wrong or bad for you.
