I am also a graduate (with scholarship) in sports journalism and a graduate in music (harmonic, piano). I speak English and Spanish. In my spare time I write scientific articles for websites and newspapers about nutrition and its relationship with sports, wellness, diseases, psychological state and childhood obesity as well as what is the nutritional value of specific foods and their relationship with our health. My favorite hobbies are geography, music, reading, writing books and hiking.
