Niki Lauda and James Hunt both loved car-race so much. So even though they lost something which were important for them, they chose to continue car racing. James lost his wife. Niki got heavy injured by car accident but he did not think about retire. Moreover he tried to return as soon as possible. If I were he, I would have retired soon. No, even I have a choise that I can become a racer driver, I do not want to be a one. This is becaue risk of death is always following them as this movie said. James always vomited up before racing, because he felt too much stress.
They always had quarrel whenever they met, but Niki and James were good rival. I think their relationship grew up through these quarrel and their race.
Thank you
