The article "Longevity Expectations and Death: Can People Predict Their Own Demise?" explores whether individuals can accurately predict how long they will live. The researchers analyzed data to see if people's expectations about their lifespan matched their actual longevity. The study found that most people tend to underestimate how long they will live, with only a small percentage accurately predicting their lifespan. This suggests that individuals may not have a clear understanding of their own mortality.
