10:05 Pyschotherapist and author Susie Orbach on why fat is STILL a feminist issue.

Susan Orbach is a psychotherapist and author of the acclaimed Fat is a Feminist Issue, which was published for the first time in 1978. Since that time it's never been out of print - underscoring the point she makes in an updated version of the book - that fat is STILL a feminist issue. But as her 2009 book Bodies points out, males too are susceptible to the pressures of being thin and the rampant commercialisation of the body. Whether it is the fashion, media, music, food, diet or fitness industries - there is no room for "fat". Susie Orbach is attending the Auckland Writers Festival in May.

11:25  Al Vernacchio: changing the way we talk to teens about sex

Al Vernacchio is a US based Sexuality educator, consultant and author. He says many of us are getting it very wrong in the way we talk to teens about sex. First, he says, is the problem with the language around sex - which is riddled with sporting metaphors like "scoring" which he says frames sex as a competition, with a winner and a loser.

The second issue, is what he calls the disaster model,  where sex education starts from a place where sex is seen as a dangerous thing -with terrible consequences.

Al Vernacchio has lectured, published articles, and held workshops throughout the US on sexuality topics. He has given TED Talks, and his blog, "For Goodness Sex", can be found on the Psychology Today website. He is the author of For Goodness Sex: Changing the Way We Talk to Young People About Sexuality, Values, and Health published by Harper-Collins. He teaches at Friends' Central School in Wynnewood, Pensylvannia.
