I’m Dayton Thorpe, UC Berkeley physics Ph.D. turned Data Scientist. In 2016, I started a private Google Doc called “How to Immortality” to keep a bibliography of medical research that I read about how to live a longer, healthier life. After reading this Nature paper that says humans can’t live longer than 115 years, I changed the title to “How to 115”. From time to time, I’d bring up my bibliography in conversation. A friend suggested I start a blog based on my bibliography, and thus this site was born. I think of this first and foremost as a collection of notes for myself on scientific results that can directly improve people’s lives, whether by making individual choices or informing policy. Sometimes other people may also find these notes interesting.
