Even though the headline says there are three risks, I’m gonna keep the first two pretty short. They are more important, but I am far from the first person to talk about them. #3, however, is much less intuitive.
Risk #1: A Portfolio That’s Too Aggressive
The classic retirement risk: you retire into a down market, you keep withdrawing what you need to live, and you’re forced to sell when the market is. The market eventually recovers, but your portfolio can’t fully recover with it — there isn’t enough money left to participate in the rebound.
This is called sequence-of-returns risk, and it’s why an aggressive portfolio stops being a complete strategy as you approach retirement. Two people can follow identical withdrawal plans and end up in very different financial situations based purely on what the market did in their first few years of retirement. Timing matters more than most people realize. This is why you need some safe investments, likely in the form of bonds or annuities (personally, I am not a fan of annuities, but that is for a different day).
Risk #2: A Portfolio That’s Too Conservative
The opposite mistake is just as costly, and arguably more common. After a lifetime of saving, many people move heavily into cash and bonds in retirement because they don’t want to lose what they’ve built. The problem is that inflation never stops working against them.
At 3% annual inflation, $100,000 of purchasing power becomes about $74,000 in ten years and $55,000 in twenty. The account balance looks stable. The actual standard of living it supports quietly erodes. Market volatility is visible and uncomfortable, which is why people overcorrect for it. Inflation is invisible, which is why it gets underestimated, especially if you have a longer lifespan than you expected.
Risk #3: Your Health — and the Hidden Variable Behind It
Healthcare costs are the biggest financial risk in retirement, and the hardest to plan for. Fidelity estimates that an average 65-year-old retiring today will spend roughly $172,500 on healthcare over the rest of their life, not including long-term care. The problem is- some spend much more than that, and is not even remotely predictable.
But the most important variable in your future healthcare costs isn’t your insurance strategy. It’s your actual health. And your health, it turns out, is shaped by far more than diet and exercise.
The Harvard Study of Adult Development is the longest-running study of adult life ever conducted. It’s been tracking participants since 1938, measuring everything from cholesterol to income to career satisfaction. After more than 85 years of data, the single strongest predictor of who stays healthy and happy into old age isn’t genetics, wealth, or even cholesterol levels.
It’s the quality of close relationships. Specifically, how satisfied people were with their relationships at age 50 predicted their physical health at age 80 more reliably than their cholesterol did. Robert Waldinger, the study’s longtime director, puts it simply: good relationships keep us happier and healthier.
The research on loneliness backs this up. One study found that social isolation increases mortality risk at a level comparable to smoking up to 15 cigarettes a day — and exceeds the risk of obesity. The friendships you maintain aren’t just sources of happiness. They’re a measurable health intervention.
Purpose matters in a similar way. Researchers studying the Blue Zones — regions of the world with unusually high concentrations of people living past 100 — consistently find that residents have a strong sense of purpose. Okinawans call it ikigai; Costa Ricans call it plan de vida. Both translate roughly to “a reason to get up in the morning.” Multiple studies have linked a strong sense of purpose to lower rates of cardiovascular disease, dementia, and all-cause mortality.
For those of you still a long way from retirement: the social and emotional infrastructure of your life is being built right now. The friendships you invest in, the communities you stay connected to, the sense of meaning you cultivate outside of work — these compound over decades, the same way a retirement account does. By the time you actually retire, you can’t quickly build what wasn’t tended to for thirty years.
