Student essay written in en (native language: French, CEFR level: B1, field of study: Sports)

Let me tell you a famous story. I'll explain you why I chosed to study sports, especially ergonomics.
After my three years of high school, I joined the french army. During my preparation, and after, my service, I developed a stong passion for sport, especially calisthenics. After my years of service, I decided to start studies. According to my journey, and because STAPS rewards people who served, I ended up at the top of the waiting list. This is the first part of my story.
Now I'll explain why I chosed ergonomics. During the first days of my college year, I attend to a presentation of all the STAPS options. I considered that four of them will not have a bright future, because to much people want to go in these options. But, nobody wanted to go in ergonomics. And, I think that ergonomics has a great future with a lot to do as it's a new discipline.
To conclude, I chosed to go in STAPS because of my past experience in the army, and I chosed ergonomics in particular because I strongly think this discipline has a bright future.
Thank you for your attention. Goodbye.
