Life and longevity are not matters that can be reduced to a simple instruction manual, however well-intentioned. A report from the Oxford Longevity Project, co-authored by Sir Christopher Ball, argues that individuals bear at least 80% of the responsibility for ill health in old age, placing the onus firmly on personal choices. Yet critics warn that such framing ignores the deeper currents — poverty, pollution, unequal access to healthcare — that determine how long and how well people live. As one reader put it, telling someone their longevity is in their own hands is “akin to telling a drowning man to pull himself together and swim, without asking what were the circumstances that put him in the water in the first place.”
The limits of personal responsibility
Sir Christopher Ball’s report, titled “Living Longer, Better,” draws on the Landmark Twins Study, which concluded that at least 75% of human lifespan is determined by environmental and modifiable lifestyle factors, and a large-scale analysis of nearly 500,000 UK Biobank participants indicating that environmental exposures and habits outweigh genetics in premature death and biological ageing. Ball, aged 91, argues that individuals can become “chief executives of their own health” through small daily decisions: avoiding processed foods, abstaining entirely from alcohol (“Alcohol is toxic, don’t drink it”), prioritising sleep, not eating after 6:30 pm, and adopting a “not-meat mindset.” He champions practices such as slow, deep nasal breathing, alignment with nature’s rhythms, and a “rest and relaxation (R&R) response” to counter stress. The report also calls for legislative action on alcohol comparable to restrictions on smoking.
But the simplicity of the message has drawn sharp criticism. Experts question whether the 80% figure translates into a meaningful increase in average life expectancy, and many point to societal factors — poverty, pollution, healthcare access — that constrain individual agency regardless of personal effort. “Life and longevity is a complex issue and simplistic solutions rarely hold water,” wrote Patrick Eckersley in response to Ball’s claims. The core tension remains: if individuals carry the blame, they may also carry the power to change, but only if the circumstances around them permit it.
Eyes in the deep: ichthyosaurs and the science of vision
Complexity also governs the natural world, where adaptations are rarely straightforward. The Natural History Museum in London has opened a new exhibition, “Jurassic Oceans: Monsters of the Deep,” featuring ancient marine reptiles including ichthyosaurs — some reaching up to 25 metres long, comparable to Dippy the diplodocus. One species, Cymbospondylus youngorum, discovered in Nevada, had a skull two metres long and an estimated body size of 17 metres, making it the largest animal from the Middle Triassic period. Visitors can touch a cast of an ichthyosaur skull, hold “Jurassic poo,” and feel casts of dinosaur claws. The exhibition also includes plesiosaurs and mosasaurs, described as the “T. rex of the sea.”
Ichthyosaurs are noted for having exceptionally large eyes — potentially the largest of any vertebrate. But as Julian Vincent pointed out in a letter, a large eye does not give more detailed vision (acuity); it provides better vision in the dark. The owl is a familiar example: its large eyes, packed with rod cells, offer excellent night vision but require neck rotation for a wider field of view. The ichthyosaur’s wide eyes, Vincent argues, were likely adapted for scouring the ocean depths and hunting in poor illumination, much like extant abyssal animals such as giant squid. The creatures also possessed an extraordinary sense of smell to track prey. Unlike other marine reptiles wiped out by an asteroid, ichthyosaurs are thought to have become extinct earlier due to diminishing prey availability linked to natural climate changes — specifically the decline of belemnites, a significant food source.
A byelection without a government champion
Political complexity is equally on display in the Makerfield byelection, triggered on May 14, 2026, by the resignation of Labour MP Josh Simons, making way for the Mayor of Greater Manchester, Andy Burnham, to stand. Polling day is Thursday, June 18, 2026. Among the candidates are Burnham (Labour), Robert Kenyon (Reform UK), Chris Kennedy (Green Party), Jake Austin (Liberal Democrats), Rebecca Shepherd (Restore Britain), Alan ‘Howlin’ Laud Hope (Monster Raving Loony Party), and Michael Winstanley (Conservatives).
Makerfield has been a Labour stronghold since its creation in 1983, with Labour winning 45.2% of the vote in the 2024 general election and Reform UK second on 31.8%. But recent local elections in Wigan — which includes part of Makerfield — show a dramatic shift: Reform UK won 24 out of 25 seats, securing 50% of the vote in Makerfield wards compared to Labour’s 23%. The by-election is expected to be far tighter than the 2024 result suggests. Burnham is campaigning on a platform of change, criticising the current path of British politics and the inability of families to afford basic necessities. Yet one reader expressed surprise that no candidate is making the case for the government’s achievements, suggesting “a Labour loyalist should throw their hat into the ring as an independent.” The absence of a government champion in a constituency that has long been Labour territory underscores the fragmentation of political loyalties.
Bread and circuses in a cost-of-living summer
Meanwhile, the government has announced a package of measures to ease the cost of living, drawing a historical parallel that one correspondent did not miss. Chancellor Rachel Reeves has proposed a temporary cut in VAT on summer attractions from 20% to 5%, applied to ticket prices for fairs, theme parks, zoos, museums, and children’s tickets for cinemas, concerts, soft play, theatre, and children’s meals in restaurants and cafes. The “Great British Summer Savings” scheme, costing around £300 million, will run from June 25, 2026, to September 1, 2026. The cost will be partly met by increasing tax on global oil firms operating in the UK. Additional measures include free bus rides for under-16s in England during August, a postponement of fuel duty increases, and suspension of tariffs on some foods including chocolate and biscuits.
Kate Nicholls, chair of UKHospitality, welcomed the VAT cut as a “positive step” but suggested further support could include accommodation. Yet the phrase “bread and circuses” — used by reader Morag Stuart in response to the announcement — evokes the Roman practice of emperors providing food and entertainment to distract the populace from political issues. The announcement comes amid reports of a sharp decline in business activity in the UK’s services sector, with businesses grappling with “a perfect storm” of political uncertainty and the impact of conflict abroad leading to soaring costs and supply shortages. Whether the summer savings are genuine relief or a distraction remains a matter of perspective, but the complexity of the economic landscape is impossible to ignore.
