How many times have you blinked? How many people were born after you? How many times did your heart beat all these years? The answers to these questions are on LifeStats (neal.fun/life-stats), a website in which users put in their birthday and are given interesting figures about their own lives.

According to the tool, a person born on February 7th, 2010, for example, has lived 3.678 days, had more or less 413.120.000 heartbeats, and blinked more than 79.500.000 times.

Aside from information about the human body, the website also shows how the world has changed since the birth of this person. In the case of the example given above, there is 6% more carbon dioxide in the atmosphere and close to 790.520.840 more humans exist on Earth now than on February 7th, 2010.

To present the figures, the platform uses data published on sites such as NASA (the United States space agency), the World Bank, and the United Nations (UN). The system was developed by the American programmer Neal Agarwal,who is a specialist in creating interactive websites with interesting information. His work includes sites about features from outer space, marine animals, and historical figures.

* The number of breaths you have taken
* The percentage of literate people when you were born versus now
