Life expectancy has doubled in a century in Spain. And in the last 50 years it has gone from 73.5 to 84 years in Catalonia. A revolution that is not only biological or sanitary, but also cultural, according to the biochemist and science communicator Pere Estupinyà. In his latest book, What do you want to be when you grow up, he explores how today's 70 years have nothing to do with the 70 years of previous generations, and argues that it is a stage that can perfectly be the best of life.
