Introduction

I decided to have a parallel blog in English to my personal one, "A las carreras" (https://lascarreras.blogspot.com/), which is in Spanish. 

So today I will publish all the entries from the month of September.

Starting with this week's entry, which will be next Friday, December 27, it will appear in "A las carreras" in Spanish and in "On the run" in English.

What is life?

Tuesday Race Friday Race   Today the weather was ideal for running, I got up early and took advantage of it with a long run. Last week, while I was wandering about the moon, the question of what life is, came up, as I often do, I dodged it. But it didn't dodge me and stayed in my mind. So today that was the topic of my wanderings. I have always liked biology. Since I was little, I have been interested in living beings, “bichos,” as I call them. I read biology books when my friends read stories, literary or science fiction novels. Despite that, I have never found a definition of life that convinces me. I am sure that almost anyone who asks, "What is life?" will answer that a living being is born, grows, reproduces, and dies. I don't think that's a bad definition, IT'S TERRIBLE. Furthermore, I didn't even like it when I was in elementary school. I mean, when an amoeba reproduces by mitosis, was anyone born? If the two new amoebas continue to reproduce by mit...

  Race on Tuesday, February 25 Friday Race, February 28   A few days ago a dear friend told me that after reading the entry “ What is life? ”, from this blog, he wondered if, based on the characteristics of the living beings discussed in that entry, viruses would be alive. I haven't stopped thinking about it for days. So in today's run I started thinking about how viruses fit into each of the characteristics that I used to define living beings, let's see. 1. It is self-contained. It has a structure that separates it from its surroundings and environment. Well… YES , viruses have a structure that separates them from their environment, but unlike the cell membrane of living beings, which is mainly composed of phospholipids, of viruses is primarily made of proteins. Furthermore, inside these, there are only ribonucleic acids, unlike living beings that have several organelles. 2. It has an exchange of materials and energy between its internal structure and what is outside (...

Race on Tuesday, January 21 Race on Friday, January 24   Yesterday I met with a group of dear friends from here, Guaymas, sitting around a table sharing some pizzas with beers and wine. At some point the anecdote came out about the first day I spent in Guaymas, in the summer of 1979. After we finished talking about this, I wondered about all the things that must have happened for the eight of us to be going through this moment of coexistence. But it was a short period, since the conversations and jokes were good. Despite having had a heavy dinner and a couple of beers, I got up in the morning with the spirit to run. My wandering was about all the things that must have happened for me to have no longer hung out with friends the day before, simply for me to be running on my 10K route on that cold January morning. I began by wondering what would have happened if on a night in mid-1977, my parents had not had some very special guests, who they recommended for me, who was finishing high...
