Ellen Mara De Wachter says collaborative art or "co-art" offers new insights into human relationships and the role of sharing in society."The co-artists who were successful in their collaborations were those who recognised and valued difference within the group...The key was not to get over personal differences, but to value them as essential to the creative process."Producer: Sheila Cook.

Franklyn Addo describes how witnessing a murder transformed his life. It made him all the more determined to help other young people from underprivileged backgrounds go to top universities, as he did, and to challenge stereotypes.

Writer Jonathan Stroud explains why he thinks ghost stories are good for you. "While it may seem odd that it's pleasurable to be frightened, it's actually - like other activities that get the heart racing - a celebration of being alive.

Jonnie Bayfield reflects on being the last generation to grow up in an analogue childhood."Looking back, I can see that no-one had any idea what the chemical, biological, or social ramifications of this burgeoning technology might be. In my school we had computer classes, but no-one ever suggested that intense use would lead to anything other than a personal and global liberation." Producer: Sheila Cook.

Matt Hood says we need to raise the standards of teaching by treating it like a performance profession where techniques are honed in rehearsal rather than tried out "live" in front of a class. "When we have low expectations of how complex teaching is, it translates directly into low expectations for how sophisticated training and development for teachers needs to be. As a result teachers learn less. That is a disaster." Producer: Sheila Cook.
