There is no other word, aside from "life", that can describe life better as I see it, maybe five minuets thinking isn't enough, hell some people do it their whole life and haven't got an answer. But as far as I can see Complicated is the best one, I am open to see if you can persuade me otherwise.
Intricate
I am bouncing off of Jack's Idea here. I think life is extremely complex, but there is a beauty about that and a sort of frailty to life adds to the beauty and wonder of living. So I think Intricate is more precise as it is detailed but also implies a level of majesty that 'complicated' doesn't. ... I spend a lot of time in my head and I like to ponder questions and ideas, so a one word summary is not an easy thing for me to do.
This also brings up an interesting idea, how much information is in 1 word and how much power does 1 word have. I mean, it is completely subjective and depends so heavily on context and what word etc. that it is not really quantifiable to a useful extent, just something I think it interesting to chew on for a bit.
Unpredictable. Anything can happen in life.It's so uncertain.Even now a bomb blast can occur in a place and kill lots of people.Rich may become beggars in a second by robbers and circumstances.An example Read this story and you may understand.
Pointless. Sure, things happen. People are born, grow up, die. Some people play piano. Some people like to eat paint. Some people will grow up to cure cancer. Now, step back a little. Here you see this rapidly degrading planet that we're wasting. You can't see all that much of the planet through the thick layer of space junk hovering about it. Step back again, and you see this solar system we know exists. And if you zoom out once more, you see this giant orbiting mass of glowing particles and space things. What does it really matter what people do?
