I saw a documentary about the oldest animals in the world. And there was something in common. These animals are the ones that consume less oxygen. NASA is carrying out a study so that its crew travel to another planet in a pharmacological coma, feeding them mechanically they could travel distances that they never imagined before. Obviously because in this way they consume less energy and live longer. Sorry if something is misspelled. I am studying English and it costs me a bit even. Hugs.
