Hello. Unfortunately, it is not possible to have access to the video "The Day I Saved a Life" and the unit to which you refer in the question above, which makes it impossible for this question to be answered accurately. However, I will try to help you in the best possible way.
According to the titles presented in the question, we can infer that the relationship between the two works is the fact that, many times, we are at risk, due to our survival instinct. Often, for it to be necessary to get rid of something that is threatening us, we need to face some risks and face some difficulties that, although dangerous, can save us. This occurs even when we see someone in danger, as our sense of survival is very strong and comprehensive.
