Episode 4: A holistic approach to healthy ageing: eyes, ears, nutrition and lifestyle

In the final episode of The Future Looks Bright we look at the importance of a holistic approach to health as we navigate the ageing process.
We meet Dug, a 44-year-old from Sydney who is confronting natural changes to his eyesight and hearing. A lifelong musician, Dug has been playing in bands since he was 14, but has recently noticed that in noisy pubs and restaurants he struggles to hear friends talking. And he's not alone.
According to the Australian Department of Health and Aged Care, about 3.6 million Australians have some level of hearing loss.
Kathryn Launchbury, a senior professional services manager, audiology, at Specsavers, says that once people reach their 40s and 50s, they are more susceptible to hearing loss. However, exposure to loud noises 'can also start damaging your hearing from a much earlier age than a lot of people expect'.
From listening to music at high volumes to the environmental noise experienced by hairdressers, gardeners and builders, repeated and prolonged noise exposure is something we should be protecting ourselves against.
In addition to eye care services, Specsavers offer free 15-minute hearing checks and comprehensive diagnostic assessments with audiology professionals.
As a result of his advancing age, Dug has also experienced some deterioration in his eyesight. He wears glasses when he's working on his computer and reading, and they're something he can't do without. Nick Gidas, an optometrist and the head of clinical performance at Specsavers, says that changing vision is a natural part of ageing.
'We're born with a natural lens inside our eye that's like an autofocus in a camera,' Gidas says. '[When we get] into our 40s and 50s, usually over a 10- to 20-year period, that lens loses flexibility and it impacts how close we can bring things to see.'
As we get older, we also naturally become susceptible to other eye conditions, such age-related macular degeneration (AMD) and cataracts.
Dr Kathy Chapman is the CEO of Macular Disease Foundation Australia. She says that while AMD isn't painful, as it progresses it's like having a 'rock obscuring your view'. Understandably, this loss of central vision has a big impact on people's lives.
In 2024 the foundation looked into how diet can help keep our eyes healthy. It can also be a factor in preventing type 2 diabetes.
Taryn Black, the chief strategy officer at Diabetes Australia, says about 60% of all cases of type 2 diabetes can be delayed or prevented through diet and lifestyle.
About 1.5 million Australians are living with diagnosed diabetes, Diabetes Australia says. And up to 500,000 people have type 2 diabetes but don't know it. The complications of diabetes are numerous, but changes in eyesight are often the first noticeable sign.
'We're always getting older, and people put [vision changes] down to a sign of old age,' Black says. 'But with half a million people living with undiagnosed diabetes, it's often the optometrist who's doing the eye check [who detects it first].'
Just as we see a GP for regular health checkups, it's also important to see an optometrist to get regular eye health checks.
While simply getting older is a risk factor for many health conditions, there are practical steps we can all take to navigate the challenges of ageing with resilience and optimism.

‘What if I just didn't drink this': the question that changed everything
For most of her 20s, Jamie* mastered the art of keeping things on the surface. She was the funny one, the party starter, the friend who never said no to another round of drinks. To friends and colleagues, she seemed effortlessly confident. But beneath the banter and bravado was a deep discomfort – with silence, with vulnerability, and most of all, with herself. 'I didn't even realise I was numbing anything,' she told me in one of our recent therapy sessions. 'I just thought I liked to have fun. But looking back, I was terrified of feeling anything real.' Jamie, now 39, is part of a growing number of Australians rethinking their relationship with alcohol. For her, drinking wasn't just a habit, it was a coping mechanism – although she was the last one to realise this. She was drinking to blur the edges. There wasn't a traumatic event that she could remember, but because feeling sad or lonely or anxious felt unbearable, alcohol helped her skip past that. It worked – until it didn't. Her 'bottom' wasn't dramatic; she told me in one session it was more like a slow hollowing, and she got tired of waking up feeling like a stranger to herself. The turning point came in the early months of the pandemic. Isolated from friends, stripped of distractions, she began to realise how often she reached for wine to fill the space. 'One night I was sitting alone with a glass of pinot, and I remember thinking – what would happen if I didn't drink this?' That question changed everything. Jamie decided to stop drinking 'just for a month'. But when the fog began to lift, she couldn't go back. She describes early sobriety as raw and revealing. She was suddenly face to face with everything she pushed away for years – grief, anxiety, even joy – and it became overwhelming. Alcohol addiction is often less about the substance itself, and more about what it helps a person avoid. From a clinical standpoint, we understand alcohol not just as a chemical dependency, but as an emotional anaesthetic – one that temporarily blunts the nervous system's distress signals. Many individuals who struggle with problematic drinking patterns may have started out chasing pleasure and to be social; but consistent reliance upon alcohol can result in using it to flee pain such as unprocessed grief, chronic stress, shame, anxiety or trauma. The neurobiology of addiction reveals that alcohol activates the brain's reward system while simultaneously suppressing the prefrontal cortex, impairing emotional regulation and decision-making. In this way, alcohol becomes a fast, accessible tool for short-term relief – even if it compounds emotional dysregulation in the long term. What makes this cycle so complex is that emotional numbing isn't always conscious. Clients often present in therapy describing 'overwhelm', 'flatness' or 'disconnection', without immediately recognising that these are signs of emotional avoidance – and that alcohol has become part of that equation. Therapy helps illuminate the underlying patterns: how early attachment dynamics, adverse childhood experiences or unresolved trauma may have shaped a person's tolerance for emotional discomfort. A trauma-informed approach encourages clients to build somatic awareness, develop emotional literacy and begin tolerating – rather than bypassing – their internal experience. Recovery, then, is not only about abstaining from alcohol; it's about being able to stay present with what's real and building a nervous system that can feel without needing to flee. In group therapy with professional guidance, Jamie started to see how she had numbed her emotions and buried the difficulties she had experienced in her life. 'I sat with just me,' she recalled. 'And I started crying and couldn't stop. It felt like every emotion I'd stored was finally being released.' I encouraged Jamie to begin journalling daily and start each entry with the question: 'What am I feeling today?' Sometimes she said it was anger. Sometimes relief. Sometimes nothing at all. Jamie finally allowed herself to feel – not with fear, but with curiosity. Our emotions can serve as signposts, gently pointing us toward the places where healing is needed: our blockages, our numbness and the parts of us that have gone quiet in the face of hopelessness. Recovery – from drinking, from disconnection, from self-avoidance – isn't linear, and Jamie is still in that process. But what's changed is her willingness to stay with herself, especially when things feel hard. Jamie is one of many emerging in what some call the 'sober curious' movement. But for her, it's not about labels or lifestyle – it's about presence. She's not interested in moralising alcohol use. It's not about judging drinking. It's about asking why. Why am I drinking? What am I avoiding? Can I support myself with awareness? And what might be possible if I stopped? In a culture where numbing is easy – scroll, sip, swipe – choosing to feel can feel too hard. It's important to take at least one quiet moment a day to ask yourself: What am I feeling? You might be surprised by the answer. * All clients discussed are fictional amalgams Diane Young is a trauma specialist and psychotherapist at South Pacific Private, a trauma, addiction and mental health treatment centre In Australia, support is available at Beyond Blue on 1300 22 4636, Lifeline on 13 11 14, and at MensLine on 1300 789 978.

Optometrist says eat 19p item now to help avoid sight loss later
The specialist said our eyes are something many people overlook when it comes to looking after their health We're told every day that diet impacts the heart, skin, and weight. But what's often forgotten is the eyes. While young people may prioritise their skin, it could hinder them in the long run if they overlook their vision. However, an eye expert says there are things we can do to help us have strong vision well into our adult life - for as little as 19p. Neil Laird, specialist optometrist at Pure Optical, said: 'If you care about your future eyesight, prevention really needs to start earlier - ideally, with your weekly shop. Age-related macular degeneration (AMD) gets talked about as an older person's disease, but by the time symptoms show up, a lot of the damage is already done." He said large-scale studies suggest certain nutrients may help protect against the oxidative stress and inflammation that gradually damage the retina over time. But he said it's not all just down to eating leafy greens and salmon. In fact, some of the most effective nutrients for eye health come from places you might not expect. What foods help make my vision better? 1. Lutein and zeaxanthin The expert suggests picking up eggs, sweetcorn and some meats to help with this - and you can pick up individual eggs in most supermarkets now for around 19p. They explain that plant-based antioxidants such as lutein and zeaxanthin play a key role in filtering harmful blue light and protecting the central area of the retina. 2. Omega-3 fatty acids These vital fats help maintain the structure of retinal cells and combat inflammation. Commonly found in oily fish such as salmon, sardines, and mackerel, they're particularly beneficial for young adults looking to establish lasting eye-health habits. For those who avoid fish, flaxseeds and walnuts provide a modest amount of omega-3s in the form of ALA. 3. Zinc and vitamin C Zinc and vitamin C work together to strengthen immune defenses and reduce oxidative stress in eye tissues - a major factor in the progression of AMD. You can find these nutrients in foods like shellfish, citrus fruits, seeds, and red peppers. Oysters, in particular, offer a rich source and are ideal for those who want to try something on the fancier side. Never do this While a healthy diet supports eye health, certain habits can speed up the progression of macular degeneration. Smoking is a significant risk factor, as it restricts blood flow to the eyes and heightens oxidative damage. Diets high in sugar, refined carbs, and trans fats are also associated with increased inflammation and added stress on the retina. 'We often blame screen time for eye strain, but what's really damaging vision in the long term is invisible - it's what's happening inside the retina,' Laird explained. 'Dietary inflammation and oxidative stress quietly build up for years. The good news is, this is one area where we really do have control, because what we eat can have a genuine, lasting impact on the health of our eyes.' Vision-friendly diet - breakfast, lunch, snack and dinner ideas • Breakfast: Boiled eggs with wholegrain toast and a citrus fruit• Lunch: Spinach and salmon salad with pumpkin seeds and olive oil• Snack: A handful of walnuts or sunflower seeds• Dinner: Grilled mackerel with steamed kale and roasted sweet potato'You don't need to cut everything out,' Laird added. 'You just need to work vision-friendly ingredients into your routine, most of which you're probably eating already. "If you want to keep reading, driving, working, and simply seeing well into old age, start now. Your eyes will thank you later.'
