Eurostat&rsquo;s expected duration of working life for someone aged 15 in the EU rose from 32.7 years in 2004 to 37.5 years in 2025; in the Netherlands it is now 44.0 years and in Sweden 43.4. The OECD expects the average normal retirement age for men to rise from 64.4 years for those retiring now to 66.3 years for those starting their careers now. The asset that has to carry all of those years is your health, and it is not expanding at the same pace everywhere. When we set Eurostat&rsquo;s 2024 working-life figures against its 2024 healthy life years, the gap between the two nearly closes in some countries: in the Netherlands, expected working life is 43.8 years against 44.5 expected years without activity limitation after age 15, a margin of 0.7 years; in Switzerland the margin is 0.2 years. Meanwhile the sprint has a measured price. WHO and ILO estimate that long working hours of 55 or more a week were linked to 745,000 deaths from stroke and ischaemic heart disease in 2016, with a 35% higher risk of stroke and a 17% higher risk of dying from ischaemic heart disease compared with a 35-40 hour week. Long hours are now rare among EU employees, but still reported by 38.5% of self-employed people with staff and 20.0% of managers. The implication is not &ldquo;work less&rdquo;. It is &ldquo;stop treating the body as a consumable in a race that is now four decades long&rdquo;.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_84 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/ceotudent.com\/en\/longevity-performance-tradeoff-40-year-career-not-4-year-sprint\/#The-wrong-unit-of-time\" >The wrong unit of time<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/ceotudent.com\/en\/longevity-performance-tradeoff-40-year-career-not-4-year-sprint\/#The-race-got-longer-verified-data\" >The race got longer: verified data<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/ceotudent.com\/en\/longevity-performance-tradeoff-40-year-career-not-4-year-sprint\/#The-binding-constraint-healthy-years-not-working-years\" >The binding constraint: healthy years, not working years<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/ceotudent.com\/en\/longevity-performance-tradeoff-40-year-career-not-4-year-sprint\/#What-the-sprint-actually-costs\" >What the sprint actually costs<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/ceotudent.com\/en\/longevity-performance-tradeoff-40-year-career-not-4-year-sprint\/#The-40-Year-Ledger\" >The 40-Year Ledger<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/ceotudent.com\/en\/longevity-performance-tradeoff-40-year-career-not-4-year-sprint\/#When-a-sprint-is-the-right-call\" >When a sprint is the right call<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/ceotudent.com\/en\/longevity-performance-tradeoff-40-year-career-not-4-year-sprint\/#The-CEO-and-the-student-over-forty-years\" >The CEO and the student over forty years<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/ceotudent.com\/en\/longevity-performance-tradeoff-40-year-career-not-4-year-sprint\/#Frequently-asked-questions\" >Frequently asked questions<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-9\" href=\"https:\/\/ceotudent.com\/en\/longevity-performance-tradeoff-40-year-career-not-4-year-sprint\/#Sources\" >Sources<\/a><\/li><\/ul><\/nav><\/div>\n<h2 id=\"the-wrong-unit-of-time\"><span class=\"ez-toc-section\" id=\"The-wrong-unit-of-time\"><\/span>The wrong unit of time<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Most performance advice is written for a quarter, a launch, a promotion cycle, or a four-year stretch at a startup.

The indicator estimates how many years a person currently aged 15 is expected to be active in the labour market, meaning employed or unemployed, over their lifetime. Changes computed by CEOtudent from the reported values.<\/p>\n<p>Two independent signals point the same way. The OECD&rsquo;s Pensions at a Glance 2023 reports that the average normal retirement age across member countries will rise from 64.4 years for men retiring now to 66.3 years for men who start their careers now, and from 63.6 to 65.8 years for women. That is roughly two extra years at the end of a career already about five years longer than it was two decades ago in the EU.<\/p>\n<p>Put together, a person entering work in the mid-2020s in much of Europe should plan for something close to four decades in the labour market. The four-year sprint is one tenth of that.<\/p>\n<h2 id=\"the-binding-constraint-healthy-years-not-working-years\"><span class=\"ez-toc-section\" id=\"The-binding-constraint-healthy-years-not-working-years\"><\/span>The binding constraint: healthy years, not working years<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Longer careers are only half the picture.

Flags from Eurostat: b = break in series, e = estimated, p = provisional. Join, subtraction and ratio computed by CEOtudent.<\/p>\n<p>How to read this table, and what it does not say:<\/p>\n<ul>\n<li><strong>Why subtract 15.<\/strong> The working-life indicator starts counting at age 15; healthy life years count from birth. Subtracting 15 assumes every year before 15 is a healthy year. Because some children do have activity limitations, the true number of healthy years after 15 can only be equal to or larger than this figure, so the margin shown is a lower bound.<\/li>\n<li><strong>Both are period measures.<\/strong> Neither predicts what will happen to a specific person. Each describes the pattern implied by current conditions.<\/li>\n<li><strong>Activity limitation is not the same as inability to work.<\/strong> Many people with a limitation work productively. The table says the two expected spans are converging, not that Dutch or Swiss workers will spend their final working years unable to work.<\/li>\n<li><strong>Healthy life years are self-reported<\/strong> and sensitive to how people in each country answer the survey question. Cross-country differences, and the flagged series breaks for Denmark, Spain, Italy and Romania in 2024, call for caution. Italy&rsquo;s high figure in particular sits on a break.<\/li>\n<\/ul>\n<p>With those limits stated, the pattern is still the most useful single fact in this piece. In the countries where careers have stretched furthest, the expected working span has grown to the edge of the expected span of life without limitation. There is little slack left. The margin is not something you can count on; it is something you have to build.<\/p>\n<p>At the other end of the career, the same Eurostat dataset shows a similar pressure. In the EU in 2024, a 65-year-old could expect 20.2 more years of life, of which 10.3 are expected to be healthy life years. The remaining 9.9 years, a CEOtudent calculation from the two reported figures, are expected to be lived with some activity limitation.<\/p>\n<h2 id=\"what-the-sprint-actually-costs\"><span class=\"ez-toc-section\" id=\"What-the-sprint-actually-costs\"><\/span>What the sprint actually costs<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If careers are long and healthy capacity is the constraint, the relevant question about any sprint is how much of that capacity it spends.<\/p>\n<p>The best-documented cost is long working hours.

It demands that they be deliberate.<\/p>\n<p>A sprint is defensible when it passes all five of these tests:<\/p>\n<ol>\n<li><strong>It has an end date you set in advance.<\/strong> &ldquo;Until things calm down&rdquo; is not an end date.<\/li>\n<li><strong>The payoff is asymmetric.<\/strong> The upside meaningfully outweighs the cost to the accounts above, and would not be available later.<\/li>\n<li><strong>Recovery is scheduled before the sprint starts.<\/strong> If recovery is left for &ldquo;after&rdquo;, it rarely happens.<\/li>\n<li><strong>The cost is reversible.<\/strong> Lost sleep for a few weeks recovers; a pattern of years does not recover on the same terms.<\/li>\n<li><strong>It is an exception, not a pattern.<\/strong> If you have sprinted in each of the last several quarters, you are not sprinting. You are operating at an unsustainable baseline and calling it a sprint.<\/li>\n<\/ol>\n<p>These tests are an editorial decision rule, not a clinical threshold.<\/p>\n<h2 id=\"the-ceo-and-the-student-over-forty-years\"><span class=\"ez-toc-section\" id=\"The-CEO-and-the-student-over-forty-years\"><\/span>The CEO and the student over forty years<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>The CEO view.<\/strong> A chief executive who ran a company&rsquo;s key asset to failure in pursuit of one strong year would be judged to have failed, whatever that year&rsquo;s result.

It is several, joined by periods of relearning. The longer the race, the more of those cycles you will run, and each one requires spare capacity: time, energy and health that a permanent sprint has already spent.

Eurostat&rsquo;s expected duration of working life was 37.5 years in the EU in 2025 and above 43 years in the Netherlands and Sweden. The OECD projects rising normal retirement ages for people starting work today.<\/p>\n<p><strong>What does &ldquo;healthy life years&rdquo; measure?<\/strong><br \/>\nIt is Eurostat&rsquo;s estimate of how many years a person can expect to live without long-term limitation in usual activities, based on self-reported limitation. It is not a medical diagnosis and it does not mean a person with a limitation cannot work.<\/p>\n<p><strong>Are long hours always harmful?<\/strong><br \/>\nThe WHO and ILO estimate links sustained weeks of 55 hours or more to a 35% higher risk of stroke and a 17% higher risk of dying from ischaemic heart disease compared with 35-40 hours. Those are population-level associations for sustained exposure, not a verdict on any single intense week. The practical lesson is that the pattern, not the occasional burst, carries the documented risk.<\/p>\n<p><strong>Who is most likely to overwork in Europe today?<\/strong><br \/>\nIn 2025, 38.5% of self-employed people with employees and 20.0% of managers in the EU usually worked 49 hours or more a week, against 3.2% of employees.<\/p>\n<p><strong>Why does the table stop at 2024?<\/strong><br \/>\nEurostat&rsquo;s healthy life years series currently ends in 2024, so the join uses 2024 for both datasets to compare like with like.<\/p>\n<p><strong>What is the single most useful change to make?<\/strong><br \/>\nMove recovery and training from discretionary to fixed. Every other rule in the ledger is easier once those two stop being the first things cut when work gets busy.<\/p>\n<h2 id=\"sources\"><span class=\"ez-toc-section\" id=\"Sources\"><\/span>Sources<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Eurostat, Duration of working life, annual data, dataset lfsi_dwl_a, and its reference metadata, retrieved September 2026.<\/p>\n<p>Eurostat, Healthy life years by sex (from 2004 onwards), dataset hlth_hlye, retrieved September 2026.<\/p>\n<p>Eurostat, Employed persons working usually long hours by sex, age, professional status and occupation, dataset lfsa_qoe_3a2, retrieved September 2026.<\/p>\n<p>OECD, Pensions at a Glance 2023: OECD and G20 Indicators, OECD Publishing, 2023.<\/p>\n<p>World Health Organization, Long working hours increasing deaths from heart disease and stroke: WHO, ILO, news release, 17 May 2021.<\/p>\n<p>Frank Pega and colleagues, Global, regional, and national burdens of ischemic heart disease and stroke attributable to exposure to long working hours for 194 countries, 2000-2016: A systematic analysis from the WHO\/ILO Joint Estimates of the Work-related Burden of Disease and Injury, Environment International, volume 154, article 106595, 2021.<\/p>\n<hr>\n<p><em>This content was compiled with the support of AI following in-depth research, then written and prepared for publication by the CEOtudent editorial team.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Working lives are getting longer while the body carrying them is not getting proportionally more healthy years. Eurostat&#8217;s expected duration of working life in the EU rose from 32.7 years in 2004 to 37.5 years in 2025, and the OECD projects the normal retirement age for men starting work today at 66.3 years. Join that series to Eurostat&#8217;s healthy life years and a hard edge appears: in the Netherlands and Switzerland, expected working life now almost equals the expected years free of activity limitation after age 15.
