Q1: Why do so many people today have unhealthy lifestyles?

There's a widespread myth that people choose unhealthy lifestyles out of laziness or lack of willpower, but I think the reality is far more structural. Modern life is designed around inactivity and overconsumption. We sit at desks for eight hours, commute by car, and live in environments where unhealthy food is cheap, convenient, and aggressively marketed while healthy food costs more and takes effort to prepare. When you work a ten-hour day and have an hour-long commute, cooking a nutritious meal from scratch feels like a luxury. We also sleep less, exercise less, and spend more time in front of screens than any previous generation. It's not that people don't know they should be healthy — it's that the environment makes the unhealthy choice the easy default. Blaming individual willpower ignores the systematic forces that shape our behaviour.

Q2: Should governments impose taxes on unhealthy food, like they do on tobacco?

I think sugar taxes and junk-food taxes are a reasonable and evidence-based policy tool, though they need to be designed carefully. The argument is straightforward: if smoking taxes reduced smoking rates, then taxing sugary drinks should reduce consumption. Several countries — Mexico, the UK, South Africa — have already introduced such taxes, and early evidence suggests they do reduce purchases of the most unhealthy products. The revenue can be used to fund public health programmes or subsidise fresh food. However, critics argue that these taxes are regressive — they hit low-income households hardest, because they spend a larger share of their income on food. That's a fair point, but it's also an argument for better design, not abandoning the policy entirely. Tax revenue can fund targeted subsidies for healthy food for low-income families, making the overall system progressive rather than regressive.

Q3: How has the attitude towards mental health changed in recent years?

We've witnessed a genuine cultural shift in how society talks about mental health, though there's still a long way to go. A generation ago, mental health problems were stigmatised, hidden, and rarely discussed. People with depression or anxiety were often told to "cheer up" or considered weak. Today, celebrities openly discuss their struggles, workplace wellness programmes are common, and schools teach emotional literacy. This is undoubtedly progress. However, there's a tension between greater awareness and the reality on the ground. The number of people reporting mental health problems — particularly among young people — has risen sharply. Is this because more people are suffering, or because more people are willing to say so? Probably a bit of both. And while attitudes have softened, access to treatment hasn't kept pace. Waiting lists for therapy are long, and in many countries, mental health care is still underfunded relative to physical health care. We've moved from silence to conversation, but not yet from conversation to proper support.

Q4: Is it the responsibility of individuals or governments to tackle public health problems?

This is a false dichotomy — both are essential, and the most effective approach combines individual behaviour change with government action. Telling people to eat better and exercise more is useless if the food environment makes healthy choices difficult. Similarly, government regulation alone won't work if people don't understand how to take care of themselves. Public health campaigns work best when they're paired with structural changes. For example, the reduction in smoking rates over the last fifty years came from multiple factors at once: public education about the dangers, restrictions on advertising, smoke-free laws, higher taxes, and support for people who wanted to quit. No single measure would have been enough on its own. The same is true for obesity, alcohol abuse, and mental health. Governments set the rules and provide resources, while individuals make daily choices. Trying to place the burden entirely on one side misses the point.

Q5: How does the workplace affect people's health?

The workplace has a profound impact on both physical and mental health, and its influence is often underestimated. On the physical side, sedentary office work is linked to obesity, back problems, and cardiovascular disease. People who sit for eight or more hours a day are at significantly higher risk, regardless of whether they exercise outside work. On the mental side, job-related stress is one of the leading causes of anxiety and depression. Long hours, job insecurity, toxic management, and the inability to disconnect from work due to smartphones all take a toll. The pandemic accelerated trends that were already visible — remote work helped some people achieve better work-life balance, while it blurred boundaries for others. Forward-thinking companies are waking up to this. They're offering standing desks, mental health days, flexible hours, and limits on after-hours emails. But many still treat health as an individual responsibility rather than an organisational one.

Q6: What can people do to maintain a healthy work-life balance?

Maintaining a healthy work-life balance is partly a personal challenge and partly a structural one, and I think people need to approach it from both directions. On the individual side, setting boundaries is crucial. That means defining when work ends and sticking to it — no checking emails after dinner, no taking calls on weekends. It also means prioritising sleep, exercise, and social connection, which are often the first things sacrificed when work gets busy. That said, individual boundaries only go so far. In a culture that glorifies overwork, setting boundaries can feel professionally risky. That's why structural changes matter too — companies that normalise after-hours disconnection, governments that enforce working-hour limits, and social norms that don't equate self-worth with productivity. The best approach combines personal discipline with a supportive environment. If you're fighting against a toxic workplace culture alone, you'll probably lose. But if enough people set boundaries, the culture itself starts to shift.
