I think it's a basic human desire to want to be in a situation that really tests your limits; just to really try your strengths to their extent and leave you empty. I've never really been in a situation like this. My life has been relatively relaxed. The only time I think that a human being will really push their limit, though, is when it is life or death for them or somebody they love.
If I could die tomorrow, without regret and having saved someone, I would absolutely make that choice. Think about it.
