Technology and Tests That Can Actually Estimate When You’re Going to Die

For decades, human lifespans have increased with advancements in medicine and technology. We also have a wealth of information at our fingertips our grandparents never dreamed of. All it takes is a quick Google search to find out virtually anything. So why not try and answer something everyone has pondered: Just when you’re going to die.

While there’s no real way of knowing when a relatively healthy person will die, there’s something shiver-inducing about seeing your supposed time remaining in hard numbers. Here we’ll look at 15 tools and other methods to predict when you’ll die. See which of the human senses can be tested to predict death within five years (page 2). And just what does mustard on your hot dog have to do with death (page 15)?

1. Death Clock

This online form will answer your biggest life question. |

This is one of the simpler death predictors. Just fill out an online form to be told the date you’ll die. Sounds pretty easy, but how accurate could this be? Yet it’s hard not to try it. Enter your height, weight, gender, age, personality, and body mass index (which can be figured out right there as well).

The Death Clock site calls itself “the Internet’s friendly reminder that life is slipping away… second by second. Like the hourglass of the Net, the Death Clock will remind you just how short life is.”

2. Smell test

Your sense of smell might be an indicator of whether you’ll still be alive in five years, research suggests. In a University of Chicago study, 3,000 people between their late-50s and mid-80s performed a smell test. They were asked to recognize scents like peppermint, orange, rose, leather, and fish.

  • Researchers followed up five years later to see who was still alive. The results:
  • Nearly 40% of those who had failed the smell test had died.
  • 19% of those with moderate loss of smell had died.
  • Just 10% of those who had a healthy sense of smell died.

Researchers concluded the loss of smell doesn’t cause death, per se, but that it could be a warning that something has already gone wrong.

3. Tikker Watch

Usually, countdowns are exciting. This one is terrifying. |

Some may love this idea, whereas others may absolutely hate it. Wearers of this digital watch see a countdown of their time left on earth. Far from scientific, it estimates your left expectancy simply using governmental statistical information minus your current age. The countdown displayed shows years, months, days, hours, minutes, and seconds.

The makers of the watch say it is a “constant reminder to live your life in the most positive way possible by seeing how fast time goes by.”

Would your life be better if you were reminded five times daily that you’re going to die? The creator of WeCroak seems to think so. It was inspired by a Bhutanese folk saying that to be happy, a person must contemplate death multiple times per day. Each notification includes a quote about death from a poet or philosopher.

The notifications come at random times between 7 a.m. and 10 p.m. — thankfully, not in the heart of night. This app doesn’t come free — it’s $.99 on Google Play and iTunes.

5. Death-predicting Supercomputer

Once patients are hooked up to this machine, it processes all their data like doctor visits, lab results, medications, and vital signs, and comes up with a diagnostic assessment. The supercomputer, developed at a Boston medical center, compares a person’s scenarios with previous results from 250,000 people in the last 30 years.

It determines likelihood of present and future medical problems like heart attack, infection, cancer, and ultimately, death — all with 96% confidence. Project lead Dr. Steve Horng said “… if the computer says you are going to die, you probably will die within the next 30 days.”

6. “How You Will Die” simulation

This tool from FlowingData is a little unique in that it shows the most likely causes of death as time goes on for people of your age and race. You can watch each cause of death’s percentages change as the years progress. Circulatory problems and cancer are up there among probable causes, but 13 others are listed as well.

7. Sitting-rising test

Developed by Brazilian physician Claudio Gil Araujo, this test illustrates that to live longer, you must move around and maintain muscle and balance. An observer assesses the participant’s ability to sit down on the floor and stand back up without use of the arms or hands. Try it for yourself.

The researchers tested 2,000 patients ages 51 to 80. They found that those who scored fewer than eight points were twice as likely to die within the next six years than those who got more than eight points; those with three or fewer points were more than five times as likely to die.

Could there really be a scientific way to determine whether a seemingly healthy person will die within five years? That’s exactly what a simple blood test sets out to do by looking for three “biomarkers.” An increased level of these indicates inflammation in the body.

This makes sense, Dr. Marla Shapiro told CTV News Channel, because “inflammation is very much part of the pathway in many diseases.” Inflammation is common for heart disease and stroke patients.

9. Deadline app

There are many smartphone apps that claim to predict your date of death. Some seem more scientific than others. One such app, called Deadline, uses statistical information to estimate your age when you’ll die. It can factor in many data points, including blood pressure, sleep, and steps.

“Deadline motivates you to be healthier … in a darker sort of way,” wrote Business Insider.

This is another simple online calculator. You enter some basic information, and it spits out the age it predicts you’ll die. It also provides a handy link to apply for a “Personal Pension” since “you’ll need hundreds of thousands more to retire.”

The calculator was developed by professors at the University of Pennsylvania. It is based on 400,000 data samples.

This website asks quite a thorough set of questions, which makes it feel more accurate than some of the others. Be prepared to tell it how much you sleep, how often you visit the doctor, how often you smoke and drink, whether you need eyeglasses, whether inherited diseases run in your family, and more.

At the end, you’re given what year your “fateful day” will come. In addition, it provides a countdown from how many years to seconds you have left.

12. Ubble test

Those between ages 40 and 70 can take the British Ubble test to determine their risk of dying within the next five years. It matches your age to a risk profile of an average person from the UK of the same gender. After you answer 11-13 questions, the site gives you your Ubble age — which may be higher or lower than your actual age. It also provides your five-year risk of dying as a percentage.

This quick test may be worth your time, as some say five-year mortality is far easier to predict than long-term morbidity.

13. Death Timer


You’ll get a personalized tombstone based on your results. |

Some may find morbid entertainment in the Death Timer website which asks for the basics and whether you smoke and drink. After you complete the quick survey, a tombstone shows up designed just for you, including your predicted year of death. Be sure to read the reason of death the program picked out just for you.

14. Death Date


What percentage of your life have you already lived? |

This online calculator has been telling people when their time is up since 2006. Visitors are greeted by a skull and crossbones and asked to fill out six simple fields. Somehow, that’s all it takes to determine the important date — as well as the number of years, months, days, and seconds remaining. And it even calculates what percentage of your life is over.

If you’re even hungry for more, the page also gives you three symbols that have a connection with your cause of death. Examples are “freeze,” “fall,” and “electricity.” This may be the most complete death predictor yet.

15. Playbuzz test

Could your favorite cookie determine your death date? |

The Playbuzz test “At What Age Will You Die?” asks some questions you probably never associated with mortality. After some seemingly on-point questions about partying and smoking, it asks you about mustard on hot dogs, cookie preferences, and your favorite season of the year. In one test result, it predicted a death age of 91 with “a full and happy life.” We definitely believe that’s accurate.
