The bioethicist who famously wrote that he did not want life-sustaining treatment after age seventy-five has a new book out that might seem at first glance to represent a change of heart. Dr. Ezekiel Emanuel, oncologist, bioethicist, and vice provost at the University of Pennsylvania, joined Dan Proft on Chicago’s Morning Answer to discuss Eat Your Ice Cream: Six Simple Rules for a Long and Healthy Life, and to clarify that the apparent contradiction is not one. He said his original essay was not about wanting to die at seventy-five but about not wanting his body to function while his brain does not, a condition he considers the worst of all possible outcomes and the thing he is most motivated to avoid. The new book is about how to maximize the chances that brain and body remain functional together for as long as possible.
The six rules begin with what Emanuel calls the most important one, which he summarizes as do not be a schmuck. The practical content is a straightforward warning against unnecessary risk-taking. He said one of his favorite examples is Mount Everest, which attracts people who treat the climb as a bucket list achievement without fully reckoning with a one-in-one-hundred chance of dying, a ratio that rises to one in twenty-five for climbers over fifty-nine. He said it is difficult to imagine a cleaner illustration of the principle than voluntarily accepting those odds for the purpose of taking a photograph at altitude.
On the wellness industry more broadly, he offered a pointed critique that the movement has made wellness itself the goal of life rather than a means toward a goal. He said the wellness influencer economy is built on self-denial and obsessive monitoring, neither of which is sustainable over the decades-long time horizon that actual health improvement requires. He said nobody maintains severe willpower-based restrictions for forty or fifty years, and that effective wellness habits have to be things people genuinely enjoy doing and eventually stop consciously thinking about, freeing attention for the things that actually constitute a meaningful life, caring for family, contributing to community, and engaging with other people.
On exercise specifically, he said the research evidence points to a clear plateau above which additional training produces no mortality benefit and begins adding injury risk. The sweet spot for health and longevity is approximately two and a half to five hours per week of moderate cardiovascular activity, which he defined broadly to include brisk walking, cycling, swimming, and dancing, anything that elevates heart rate and breathing. He said an Iron Man triathlon is a legitimate personal pursuit if someone is passionate about it, but it is not a health strategy and is not required or even recommended by the evidence. He is himself an avid cyclist who regularly rides forty to fifty miles on weekends at seventeen to eighteen miles an hour, sometimes accompanied by his wife.
He said social engagement is one of the most underrated elements of healthy aging and his preferred vehicle for it is hosting dinner parties, which he called a wellness trifecta: cooking new dishes challenges the mind, preparing food with vegetables and fruits supports good nutrition, and the extended social interaction of a two-to-three-hour dinner produces the kind of human connection that research consistently associates with longevity and cognitive health. He said the parties typically end with chocolate rather than ice cream, though he defended ice cream as genuinely good for you, noting that research associates dairy consumption with reduced diabetes risk and that the blanket assumption that enjoyable foods are bad for health is frequently not supported by the evidence.
Proft asked him to weigh in on Samuel Moyn’s new book arguing that older Americans are hoarding disproportionate wealth and political power at the expense of younger generations, and Emanuel said he agrees with the basic thrust. He said older people hanging on to positions of authority and economic resources and boxing out younger people who are at their most creative and energetic is a genuine problem, and that Congress has provided embarrassing examples of members who are clearly not mentally functional continuing to hold office. He separated the valid case for managing generational succession from the question of individual exceptions, acknowledging that Benjamin Franklin invented bifocals at seventy-nine but insisting that exceptional individuals like Franklin do not establish the norm and that policy has to be designed for the norm rather than for outliers.
On the Affordable Care Act, Emanuel pushed back on the Wall Street Journal’s argument that Obamacare is responsible for current healthcare affordability problems. He said healthcare costs as a percentage of GDP were essentially flat from 2009 through 2023, a period he attributed largely to the ACA’s structural reforms, and that Medicare pricing changes under the law saved approximately four trillion dollars that went toward deficit reduction. His criticism of the current situation is directed at the fifteen years during which Republicans made no constructive revisions to the law while attacking it continuously, and he said blaming the ACA for problems that accumulated during a decade and a half of deliberate policy neglect is not analytically honest. He said the law needed revision from the beginning, as any major policy does, and the failure to do that work is the source of most of the problems critics now cite.
