What is life?

I constantly hear people sigh "What is life?" and now of course (as you can tell by my previous posts my brain works in a funny way) it has got me thinking what does this shrug of the shoulders quote really mean?
Are we genuinely asking "What is life? " 'Why were we made?" What are we meant to do here?" Or are we literally just putting our middle finger up to the world and thinking I am so done with today!
I use my "What is life?" mostly when I'm thinking the second option...but saying that, it really does make me think what are we meant to be doing with our lives?
I know you must read multiple posts on Facebook or Twitter stating how we aren't just here to work our asses off and then die! No really?! I would never have guessed that... Wow what a lovely world we must live in that allows us to live how we want and not work and then die, how brilliant! Well im not sure about you guys but I don't think that lovely world really exists.
I'm not sure if it shocks anyone else as much as me when I see or hear the things that are still happening today in this century that should have become extinct years and years ago. Like seriously?! Everyone keeps banging on about how 'times are changing' but look at the real issues here.
Domestic abuse, poverty, the boundaries between rich and poor are all still around us, STILL in the 21st century we have these problems! Problems that shouldn't have even been around in the first place.
Now my goal in life is to help people. I believe that is the most important thing anyone can ever do. Each and every one of us, our life purpose should be to help people. If everyone had that mindset do you think we would still be having these problems? I believe not.
Find a goal. Choose it. Life it. Help others, be kind, share your life, try and make people happy and maybe then you can stop asking yourself...
