Is your life worth living or is the life you are living, worth calling a 'life'..?

Did you ever imagine what the heck we are doing here? 24 years have spanned and unaware of how much more to come..lost few very dear ones, gained few very sweet ones..and no idea when the loop of this life will merge its initial point. Well I really assume life to be a circle, starting from a point and can have different curvatures all along its path till it reaching its end. Sometimes it climbs a steep curve, sometimes it rushes down, some flat for a while...
So all this analysis is worth analyzing? Absolutely yes. Humans are not like any other creatures, who are unaware of their birth, their death, unaware of what they do every moment. Almost everyday when I drive to and from work, I encounter small helpless animals(sometimes squirrels,sometimes cats, sometimes something I have never seen before) that had been buried above the road, with their bodies lying flat teared out. For instance when I was returning yesterday, 4 small squirrel like creatures were playing on the road. May be they were five or more but one had already seen the fate. They caught my attention long before and so I slowed down. One among them hurriedly ran from the pavement and sat right in the middle of the road showing me his back. I managed to take a cut and slowly pass him through. Did he analyze what his fate could be at that time? How important was his life to himself? What was his aim in life after he got a new breath escaping my car tires? No he doesn't care about all this radical thinking stuff, or probably he just don't have the ability to do it.
Do you and me have this ability? Do we know the importance of our lives? Being a Muslim at least we know why we are here and we will definitely see death in any form anytime. Then why do we still neglect this very truth of our life? ...Forget your wallet a day, why do you care to turn back and get it? You just want to be prepared if a cop catches you or if you go out of gas(petrol).i don't want to go again in the same topic I had before about our luggage to the heaven(or hell).
Every now and then, I look at my own life and compare it with the victims of the recent earthquake in china, the flooding in Myanmar, the everyday killing in Palestine and Iraq. Those people are also humans like us, they have been gifted with the same body and soul as us. Then why are they not given a CHANCE as what we enjoy...hmmm do we realize that we really got a chance? Are we the lucky ones? In what way?
By now you should at least get the answer to the last question...
