How long can we live?
The Inquiry
Apr 4, 2019

Life expectancy is going up as we develop new cures for the diseases that kill us off. But can we beat the most fatal condition of all - old age? We talk to scientists on the frontier of fighting the ageing process itself, when our bodies just start to wear out. In India, Tuhin Bhowmick is working towards 3D printing new organs so people don’t die waiting for transplants. In the US, Meng Wang is developing ways to use the tiny creatures that live in our guts to extend our lives. And in the UK, Lorna Harries and her team have made an amazing discovery that could let us roll back the ageing process in our own cells.

But is there an upper limit to the human life span? With all these advances racing ahead we ask – how long can humans live?

Is time up for TikTok in the US?

In January, the popular Chinese social media app TikTok went offline for its 170 million Americans. The outage marked a turning point in a long-running dispute over data privacy and national security, with US lawmakers concerned about the app’s Chinese ownership. A law passed by Congress required ByteDance, TikTok’s parent company, to sell its US operations or face a ban. Although ByteDance did not meet the deadline, the newly inaugurated President Trump postponed enforcement, introducing a timeline for a potential sale. That deadline has since been extended multiple times, with the current cutoff now set for 17 September. But with complex negotiations still underway and Beijing reluctant to approve any deal, Trump has signalled he may grant yet another extension leaving the app’s fate in the US uncertain. This week on The Inquiry, we’re asking: Is it time up for TikTok in the US?

Is Japan moving to the right?

A far-right party which came to prominence during the Covid-19 pandemic recently showed itself to be a contender to Japan’s centrist political establishment, when it grew from one seat, three years ago to 15 seats in the recent elections.

Known as Sanseito, the party is led by Kamiya Sohei, whose YouTube videos spread conspiracy theories about vaccinations. Its political platform is a nationalist ‘Japanese first’ agenda and warns against a ‘silent invasion of foreigners’.

Whilst for Japan’s ruling Liberal Democratic Party coalition, the election results were bruising. The LDP lost its majority in the Upper House, having already lost control of the Lower House last year. But its embattled Prime Minister, Shigeru Ishiba, whilst facing calls from within his party to resign, has said he has no plans to quit.

Against this backdrop, there’s a growing unease amongst Japanese voters over issues like immigration, over-tourism and the economy and Sanseito are tapping into that.

Joining us to discuss Japan's political climate are Kenneth Mori McElwain, professor of Comparative Politics, University of Tokyo, Japan; Dr Fabian Schäfer, chair of Japanese Studies, Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany; Jeffrey Hall, author and lecturer, Kanda University of International Studies, Eastern Japan; Dr Kristi Govella, associate professor of Japanese Politics and International Relations, University of Oxford, UK.

Can Indonesia afford free lunches?

Children in Indonesia are now receiving free school meals — part of a bold new plan by President Prabowo Subianto to tackle malnutrition. Around one in five children in the country are stunted, meaning they are too short for their age. The lunch programme is central to Prabowo’s vision of a “Golden Indonesia” – a prosperous, high-income nation by 2045. But not everyone is happy. To fund this and other populist pledges, the president has reallocated billions in public funds, cutting budgets from ministries including health and education. There have also been reports of food poisoning linked to the programme. Meanwhile, millions of Indonesians are struggling. The International Monetary Fund warns the country's unemployment rate will rise to 5% this year — the highest among the Southeast Asian economies it tracks. On this week’s Inquiry, we’re asking: ‘Can Indonesia afford free lunches?’ Contributors: Dini Widiastuti, Executive Director, Yayasan Plan International Indonesia Julia Lau, Senior Fellow and Coordinator, Indonesia Studies Programme, ISEAS – Yusof Ishak Institute, Singapore Dr Suman Chakrabarti, Associate Research Fellow in the Nutrition, Diets, and Health Unit, International Food Policy Research Institute, New Delhi, India Bhima Yudhistira, Executive Director, Center of Economic and Law Studies (CELIOS), Indonesia
