How do you view it? = Meaningful because I share it with people special to me.
Why do you continue to live? = I'm sharing my life with people close to my heart. I won't bail out.
Do you value any other person's life? = Yes, as much as some others value mine.
Would you sacrifice your life to save another? = After watching "Right At Your Door" (2006), I really thought about things along the lines of your question. I advice you watch it if you haven't. To answer the question, I can't really say yes but, I have to say that I won't live at the expense of another person's life especially a loved one.
I live because at this point it takes more effort to die than not, and I want to know what happens. I want to know what death is like too, but I want to experience all that life has before I give it up to answer another question.
I'm pretty chicken-shit so I'm not sure if I'd make a very good self-sacrificing body guard. But I've never had to seriously consider the decision before so I have no idea if I would.
I am a solipsist. Thus life in the plurality of a person and an environment is mostly just an aspect of my existence. Life, along with every other part of existence, is a fallacy; an illusion, if you like.
I continue to live because in this current state I only understand the world as described above. And I want to live it through that way.
The value of my personal life can be compared to that of the aspects of my environment, which, in the end, is indifferent from who I am. Thus, there are situations when the most suitable choice is to destroy the individual perspective for an expected outcome (e.g. redemption of something greater).
It just is. I'm alive because it's actually pretty hard to die - I think I recall only about 16% of suicide attempts are successful. Mine weren't, obviously. Your instincts for survival still work if you're unconscious, did you know? I'd say it's by far the most powerful instinct we have.
Life is what you make it. If I had no-one else that depended on me and no friends at all then I would not continue. Would I sacrifice myself, yes for my partner and children if there was no other way to save them.
Considering I'm Christian, I say life is meant to be lived out in a way that is both pleasing to the Lord and we must enjoy the good things that the planet has to offer. I respect other people's lives unless ofcourse somebody is purposefully trying to end my own. One of the commandments is to not murder. It isn't murder when you are protecting your own life. Unfortunately, I don't know if I would have enough guts to say, push someone out of the way of an oncoming car. Shameful, I know . I continue to live so that I can continue to be a service to God and to do all of the things that would complete it. which would be in this order. Get a job that I like, get a girl friend, marry said girlfriend if she is the right one, start a family, and finally pass on whatever I have to offer to my kids.
I view life as a gift, full of chances, lessons, mistakes. I continue to live to spread love and happiness in any way I can. I live to find some answers to the many questions I have. I want to think I'm able to make a difference.
I would sacrifice my life for another. I believe it's in vain not to.
