What is it like to witness a serious crime or traumatic event? And how reliable are eyewitnesses? Jenny Brockie meets Westgate Bridge murder witness Michael Piacentini; workplace murder witness Robert Strange; KA Whyte, who testified in the manslaughter trial of former Comancheros bikie boss Mick Hawi; and forensic psychologist and UNSW professor Richard Kemp.

Jenny Brockie explores the stories of five women who speak about discovering their partners' other lives, and how they dealt with that deception.

How are couples making marriages work when they've met online, lived in different countries and don't share a common language? Seeking out a foreign husband or wife is nothing new - hopeful singles have long looked overseas for a suitable spouse, and maybe a better life. But thanks to the boom in online and mobile dating, it's never been easier to look for love further afield. And while local dating sites and apps mean you're only ever one swipe away from your next hookup, the stakes are considerably higher when you're wooing someone in a foreign country whom you've never met and don't share a language with. Not all is fair in love and visas. Marrying someone after a short period of time can be a big risk, and it can be difficult to know if you're being taken advantage of. And getting to know your new partner when you don't have a common language can be a problem that persists for years. With international dating sites reporting growing subscriptions each year - along with the rising number of couples meeting and marrying through them - Insight asks: Why do people look for a partner overseas? What happens when they find one? And how do they make it work?

Jenny Brockie takes a look at what happens when sexual assault is reported and the alarming numbers behind it. She speaks to victims of sexual assault, and they discuss their lives post-attack. Victims tell Insight that while the process can be traumatising, changes to the legal system have made it easier to go through it in some cases, but often the cross examination process is a reason why some never want to see the inside of a court room.

How do young people get on with life after having had cancer? With technology improving, currently 88 percent of teens and young adults will fight off cancer but two thirds of those survivors will experience at least one chronic health issue as a result of their treatment. Insight examines why dealing with cancer is different for young people. We ask what it's like dealing with the physical and emotional scars left by what could have killed you, and does that experience change when you still have so much life left ahead of you?

When 40-year-old Emma swiped right on Tinder at work one night, she wasn't expecting the first date to result in a baby, but it did. Once the initial shock of finding out she was pregnant had worn off, Emma found herself coming to terms with being bound to a stranger for the rest of her child's life. She's now co-parenting her six-month-old daughter with a man she's still getting to know. In this episode of Insight, we hear from a number of women and men whose one-night stand, fling or 'friends with benefits' hook-up accidentally resulted in parenthood. But is a 'Tinder surprise' baby just a modern label for an age-old issue that many face at some stage of their lives - an unplanned pregnancy? This Insight episode asks, what's it like having an unplanned child with someone you hardly know?

How far can you push your body until it hits a wall? More punters are testing their limits of endurance, but at what cost? Insight talks to competitors about what drives them to the edge.

Nearly 2 percent of Australians have some sort of intersex variation. It's as common as people with red hair. Intersex advocates are calling for a ban of surgery on intersex infants and say procedures on people before they are old enough to consent are a violation of human rights. However, doctors say any ban would affect many families and individuals who are happy with the surgery they had as children. This week Insight speaks to people who are intersex about how they navigate life and the medical system.

What's it like growing up in a stepfamily? Every family has inherent tensions but what happens when your parents split up and re-partner and your family now includes a stepparent and their kids? Just over a quarter of a million Australian kids now live in stepfamilies, but combining children from different parents into one big family can be full of surprises and challenges. Insight meets a stepfamily of seven kids ranging in age from 12 to 18 who call themselves "The Brady Bunch plus one".

Where do women draw the line on sexual harassment in the workplace? Compliments about what people are wearing, jokes, and even flirting are a normal part of most workplaces. When does behaviour cross the line and become sexual harassment? How much does it matter who the person is? The majority of people who experience sexual harassment do not report it, according to a national phone survey. Hear the lengths people are going to in order to avoid making an official complaint. What would you do if the person harassing you was in a more senior position, or your boss? If inappropriate behaviour is common in your workplace, how do you change an entire culture?

Are we entering the age of no retirement? The age we can access the pension will rise to 70 by 2035. Many of us are living longer and healthier lives so the expectation and reality is that most of us will work on later in life. But that's not always easy as age discrimination, health issues, caring responsibilities and attitudes towards growing older often get in the way. Many older Australians need to work and want to work but are being forced out of the workplace and finding it hard to get back in. This week Insight examines how we remain engaged, relevant and productive at work as long as we want to and need to.

Recent statistics from the Foundation for Alcohol Research and Education show drinking is on the rise among mid-life women. Why are women drinking more in later life? This week, Insight explores the reasons why.

Judges, barristers and court transcribers reveal what it's like to work in criminal law, from how they handle the sordid, lurid details to the complex, nefarious characters they come across.

How old is too old to have a child? This week on Insight we explore the trend of the older parenthood. Is it better late than never? While Australia's overall birth rate continues to fall, older mothers are bucking the trend. The fertility rate for mothers aged 45-49 doubled between 2004-2014. We speak to older mothers, including comedian Mary Coustas, who became a mother via IVF at 49; older fathers such as Kevin King who became a dad again at 70; and the children of older parents such as Ozzie Colley whose father was 92 at the time of his birth.

How do you rebound from failure? Failure - we fret it, we shun it, and we question ourselves whenever it happens. But can failure be a blessing in disguise? Former Socceroos skipper Paul Wade, Showpo's Jane Lu, the Leyland Brothers' Mal Leyland, and Miss Chu's Nahji Chu join Insight and discuss the concept of failure. How does it feel to lose everything? And what does it take to bounce back?

How do you deal with the unanswered questions when someone you love goes missing? This week on Insight: living with the unknown when someone you love goes missing. Australia has around 1800 long-term missing people. For their families and loved ones, the ambiguity surrounding their fate can be a living nightmare. 'Ambiguous loss' differs from the grief experienced when a loved one dies because there is no verification of death, no body to mourn. It freezes the grieving process and prevents resolution. And it can get worse because you don't have all the pieces of the puzzle to accept what's happened. This week Insight takes you inside the lives of families living with ambiguous loss.

Every day, we encounter different messages and strategies about how to live a healthy lifestyle. Public health messages aiming to address the obesity epidemic have increased our health awareness, while bloggers and social media personalities share their advice on what they think is best for our bodies. Almost two thirds of Australians are overweight or obese. But disordered eating, according to some experts, is on the rise and in need of more attention. What happens when the drive to be healthy becomes unhealthy? This week on Insight, we hear from people whose healthy habits have strayed into the dangerous territory of disordered eating. At what point did they tip over into being unhealthy? And how have they dealt with it?

Why do so many Australians have poor literacy? We may not be aware of it, but most of us know someone who struggles with reading and writing. Around 44 percent of adult Australians have literacy levels that make everyday tasks - like filling out a form or reading a prescription - very difficult. Sadly, our numeracy levels are worse with over half of Australian adults scoring low on international surveys. Literacy standards in 21st century Australia have increased dramatically. Computers and our digital age demand high-level literacy skills, while jobs that may have required minimal reading or writing now involve extra checks and balances like filling out OH&S reports. But low literacy goes far beyond simply being able to read and write. Individuals with gaps in literacy are more likely to be vulnerable to social exclusion, and unemployment. Businesses also suffer with 93 percent of employers reporting low levels of literacy and numeracy were impacting their business. Yet despite almost one-in-two people having gaps in their literacy skills, this world remains largely hidden to those of us who are lucky enough to be confident in our reading and writing skills. This week Insight speaks to a number of Australians from all ages and backgrounds who have lived a life with low literacy in a world that assumes that they don't exist.

Why are more older women becoming homeless? This week on Insight, we reveal the true extent of a hidden issue: women and homelessness. Australian Institute of Health and Welfare data shows the number of women over 55 accessing support for homelessness is increasing at a faster rate than it is for men. Experts say this is a growing problem that should be getting urgent attention from policy makers. Support services say women in this age group are more likely to be the hidden homeless; not sleeping rough on the street but house-sitting, couch-surfing, living in cars or moving between their friends' and children's homes. Many of these women have led 'traditional' lives - they've been employed most of their life, raised children, cared for ageing parents and paid taxes. But as they age, their health deteriorates, work opportunities slow and rents rise, they find themselves unable to afford a roof over their head. Our guests explain how it could happen to anyone. Di Hill, Christine Kent and Kath Reynders share their stories this week on Insight; the stories of the increasing number of older women on the edge.

Are our soldiers equipped for the transition to everyday life? Veterans groups say around 30 percent of veterans in Australia are unemployed. That's much higher than the national unemployment rate of 5.6 percent. A veteran's problems can often be made worse when applying for compensation with the Department of Veterans Affairs with some claims taking years to be processed and paid. The RSL was once the place veterans turned to for support after their service but that's changed. There are now more than 3000 ex-service organisations and many veterans say the RSL is outdated doesn't represent the modern veteran. This week, Insight speaks with veterans James Hancock, Kiel Goodman and Brad Watts to see how prepared they were for civilian life and what can be done to make it easier.

Please note this episode contains descriptions of alleged sexual assault. "What happens if you decide halfway through sex that you don't want to do it?" asks Insight host Jenny Brockie. This week on Insight, young people dish the dirt on sex and sexting. Not the mechanics of it, but what it's like to navigate sexual encounters and how you work out whether or not you've got the green light to go ahead and have sex.

What's it like growing up with a sibling with a disability? Around 1.4 million Australians have a profound or severe disability. Siblings play a vital role in their early lives, but little is known about their experience. How do they view their relationship? What role do they expect to play in their brother's or sister's adult life? This week on Insight, we hear how Jodie Chambers, Luke Thorne, Sarah McCarthy, Yvonne Whittaker-Rush and other siblings deal with the many and varied experiences of growing up and growing older with brothers and sisters with disabilities.

More and more single women are making the choice to become solo parents. As fertility deadlines approach, a new generation of women aren't prepared to wait forever for 'Mr Right' to come along and risk missing out on the opportunity to have a child if a partner doesn't arrive in time. So Plan B is now a popular option: to go it alone with the help of a sperm donor. IVF clinics around the country are reporting the demand for donor sperm by single women is soaring as women are taking things into their own hands and fulfilling their dreams of being a mother. We speak to a number of women and men who've chosen the donor sperm and surrogacy path, about the joys and challenges of solo parenting. We also speak to those in the process of trying to become solo parents via IVF and the children of single mothers by choice to reflect on the long-term implications of being brought into the world via donor conception. On Insight this week, we examine the growing child-rearing trend of solo parenting by choice.
