Ageless has over 400 references, most of which are scientific papers but also including other books, press articles, videos and reports. The easiest way to access these is the short links in the back of the book, which start with and are followed by a unique code made up of six letters and numbers (eg If you type this into a web browser, it will take you to the reference, occasionally with additional information. For completeness, I’ve also added chapter-by-chapter reference lists, which you can access below.

Data and calculations

I had to calculate some statistics in the book myself from publicly available data. The simple calculations are in Google Spreadsheets which you can find in this Google Drive folder. The more complex calculations which required scripting are available in this GitHub repository.
