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.
Foreman won world titles in 1973 and 1994
Here, former two-time heavyweight boxing champion George Foreman gives his view.
Children are patient, they never give up on you.
Adults sometimes forget, and they push kids - and if they don't get it straight they be spanked - but kids will continuously be patient with teaching adults.
I don't think there's a big difference in growing up today than how it was when I was young.
There's a lot more of a lot of things today, but basically children are children. Teenagers still look for something sweet - a dance and a date, it's no different.
When I was young, the launch in of the Popeye cartoon had the greatest impression on me. All of a sudden it's "Popeye the sailor man!"
I'll never forget that cartoon - I found out everything about laughing.
The greatest memory of my childhood was my father putting his hand on my head and saying, "George Foreman! The next heavyweight champion of the world! Stronger than Jack Johnson, he hit as hard as Jack Dempsey." I was about four or five years old at the time.
What I try to advise my children is listen to the older generation. Don't ever get to the point where it's boring to listen to people older than you.
Their secrets that they have - you're going to run into the same stumbling blocks, nothing different.
