It's the first full week of life in the wilderness and the therapy gets well and truly underway. The course is deliberately designed to be physically tough. Only when the camp sees the family dysfunction in action will staff know what they are working with. The usual routine of hiking and camping is added to with a unique therapeutic tool: llamas. As pack animals they are stubborn, unruly and a law unto themselves, not too dissimilar to defiant teens in fact!

In our middle years, some of us are faced with an ultimate fight for life as our bad habits and lifestyles take a massive toll on our bodies. Allen is 53 years-old and is walking around with a ticking time-bomb deep inside as doctors find a dangerous aneurism growing in his stomach. Nick is 52 years-old and his body is about to unleash a fatal blow as a blood clot lodges in his brain causing a stroke. And 58 year- old Christine - a heavy smoker - is rushed to hospital as she literally cannot breath.

We all think we know what ageing is, but it's actually surprisingly difficult to pin down. In this program, a 70-year old fashion model and her 17-year old granddaughter take part in scientific test to see whether it is possible to distinguish between them. The results give an insight into what contemporary science can tell us about what happens when we age at the molecular, genetic, cellular, physiological and psychological level.

Twenty years ago, Aussie battler Brian Cox was a street derelict drinking aftershave, methylated spirits, ammonia; just about anything that would get him drunk. But these days Coxy is a man on a mission. Through some kind of miracle he got sober and has since dedicated his life to getting Melbourne's most chronic alcoholics to do the same. At a time when binge drinking is on the rise, we go inside his unique rehab to meet the people he helps and follow them and Coxy on the road to recovery. Broadcast as part of SBS's Secrets and Lives series.

A typical teenager goes to bed late, and can't get out of bed in the morning. But while many adults regard them as layabouts or lazy, the reality is most teens need more sleep not less. Experts say adolescents require between 9 and 10 hours sleep a night - but only a small fraction get this much.

When your child turns into a teenage brat, who exactly is responsible and how can you, as parents, help to turn things around? Rather than just sending them off to the American wilderness to fix their out of control behaviour, in Family Brat Camp the parents go too. And in this first episode living and sleeping in the wilderness comes as a major shock, not only for the brats, but for the parents as well.

Presented by Steve Leonard we look at how life conquered a hostile dry world and how a string of chance events and global catastrophes led from a fish to a human.

Rare chicken breeder Mark Tully goes on a 10,000km journey across Australia to track down endangered poultry. He has more than 200 breeds among his 2000 chickens, which he claims have saved his life. Tully has battled with depression and has been so low that he became a recluse for nearly five years. The only thing that enticed him out of the house was caring for his beloved birds.

Science reveals that irrational, inexplicable teenage mood swings aren't only normal, they're helpful and beneficial - even if they are painful for parents and teens alike. Teenagers may be sulky and surly one moment, exuberant and ecstatic the next. And it's more than hormones that brings on these extreme teen mood swings, it's their developing brains that are also to blame. Teens are at a cerebral crossroads; their brains driving new ways of thinking and feeling, and how teens learn to manage their moods can either empower or derail them for the rest of their lives.

Darwin gave us the most sensational idea in biology: evolution by natural selection. But even he knew that it came with difficulties. Tracing the history of these ideas, this program uncovers the accuracy of Darwin's theories.

Teens are re-writing the rules of sex but while their bodies suddenly become adult, they're not necessarily in sync with their chief sex organ - the teen brain. Whether they're having sex or not, whether their parents like it or not, teenagers are sexual beings. Today's teens are having sex earlier, clocking up more partners and are more sexually adventurous than ever. It all starts with puberty, the human sexuality switch, but it's the teen brain that drives this change, influencing teen sex lives in surprising ways.
