The headline “If You Reach 60 Without These 5 Diseases, You Have a High Probability of Living to 100!” contains a kernel of truth but makes an unwarranted promise.
Research does show that people who eventually become centenarians tend to have fewer chronic diseases and later disease onset than people who die earlier. But there is no medically validated checklist of five diseases that lets you predict at age 60 that you’ll reach 100.

The five conditions usually meant by headlines like this
They generally refer to:
Heart disease
Stroke
Cancer
Diabetes
Chronic lung disease/COPD
These conditions are important because avoiding or delaying them is associated with longer survival. But having one doesn’t mean you can’t live to 100. Studies of centenarians show that many people survive chronic diseases for decades, while others develop them much later.

In one U.S. study, about 43% of centenarians had experienced a major chronic disease before age 80, while others delayed disease until their 80s or 90s; about 23% reached 100 without a major chronic disease.

What matters more than simply avoiding disease?
If you’re around 60, some of the most useful things you can do are:
Don’t smoke and stop if you do.
Keep blood pressure and cholesterol under control.
Maintain a healthy level of physical activity, including strength and balance exercise.
Keep diabetes under good control—or prevent it when possible.
Eat a nutritious diet emphasizing vegetables, fruits, whole grains, legumes, nuts, and adequate protein.
Maintain healthy social connections and stay mentally and physically active.
Get recommended screenings and vaccinations.
Address hearing, vision, sleep, and mobility problems rather than simply accepting them as “old age.”
And here’s the surprising part
Reaching 100 doesn’t require being disease-free. Research on centenarians shows considerable variation: some remain remarkably healthy, while others live many years with cardiovascular disease, diabetes, cancer, or other chronic conditions.

So a better version of the viral headline would be:
“Avoiding or delaying major chronic diseases can improve your chances of a longer, healthier life—but no one can predict at 60 whether they’ll reach 100.”
The goal isn’t just lifespan (years lived), but healthspan—remaining independent and functional for as many of those years as possible.
