From the moment your heart stops, your body begins a precise, predictable sequence of changes. Here is the science of what happens — hour by hour, day by day — after death.
Bulgaria, Chad, and the Central African Republic top very different lists. Here's why crude death rates and age-standardised death rates tell completely different stories — and what each reveals.
Dementia now kills 2.5 million people per year and has become the 7th leading cause of death worldwide. Here is what is driving the rise and what the numbers reveal.
Adopting five simple habits can add 12-14 years to your life expectancy, according to a landmark Harvard study. Here is the data on what works, how much each habit matters, and why it is never too late to start.

An estimated 117 billion humans have ever been born. About 109 billion have died. The 8.1 billion alive today are just 7% of everyone who ever existed.

Cardiovascular disease kills 18 million people per year — one person every 1.7 seconds. Here is why it dominates every other cause of death and what the data reveals.
Heart attacks are 20% more likely on Monday mornings. Suicide rates peak on Mondays. The data reveals a deadly pattern hiding inside the work week — and it disappears when you retire.
Your risk of dying changes dramatically as you age — and what kills you changes too. Here is the full breakdown by decade, from infancy to old age.
Diabetes kills over 2 million people per year and the number is rising faster than any other major cause of death. Here is what the data shows.
Around 13,700 children under five die every single day. Most of those deaths are preventable. Here is what the data shows — by cause, by country, and by what actually works.
Air pollution kills roughly 19,000 people every single day — more than car accidents, smoking-related lung cancer, and malaria combined. Here is what that number really looks like.
Alcohol kills about 8,200 people every day worldwide. It is involved in over 200 diseases and injuries. Here is what the data actually shows.

Men die 5 years younger than women on average, and in some countries the gap is over 10 years. The reasons are biological, behavioural, and systemic.
Your liver has no nerve endings — it cannot feel pain. But your feet often show the warning signs years before any test does. Here is how to read them.
