About the Book:

This book is about life. It is about existential questions, science, and spirituality. It does tell a story. It is not an essay. It is written in a way that allows non-specialists to understand it and to be enjoyable as literary non-fiction. However, its academic rigor has been maintained throughout the text. It is a memoir. Therefore, all the adventures truly happened. I am a male biologist. I describe the cultural experiences that I lived while growing up in Mexico between the years 1984 and 2002. I also discuss my later life in the United Kingdom and Sweden. During this time, the 2000s culture is explored. This text was not written or illustrated using artificial intelligence.
