Think of the one item in your life you could not do without, and then explain how you would do without it if it didn't exist.

what item could i not live with out, to choose one item would mean first assuming what kind of item that may be... an item could be among things a comestible? an 'item' of clothing, a form of shelter, the 'item' being a roof perhaps... could oxygen and a pillow signify as itinerary to aid with breathing and sleeping but of course me instantly assuming something i can't live without in the form of an 'item' would be something that is intrinsic to my own survival might be taking the subject too far...
the question couldn't just be a case of something i could survive without as it goes on to ask how i would survive without it's existence.
if oxygen would to be absent from the atmosphere then as living things perhaps life would end as it does seem quite essential or perhaps the world would adapt to exist without oxygen existing in a world. we'd all breathe in argon or neon gases or maybe nitrogen, there is plenty of that in the atmosphere.
if food didn't exist we'd subsist off off something else or die... after pondering the existence of the phrase item i reckon something i could not do with out is soap.

i could survive without hygiene but i choose not to.
one thing in the world that makes me more content than my usual nonplussed self is being scrubbed thoroughly clean. nothing feels better than water washing away all the dirt, the sweat, the dead skin... after a shower you feel new and fresh and free, brushing my teeth before i go out puts me in a bright mood.
i can go a day without eating or sleeping and feel perfectly fine but i can't last very long with out having a hot shower.
if all the cleaning itinerary were not to exist and we as humans were fine with just living in our own waste and filth i'm sure i'd become accustomed to that way of life but just being clean is a really good feeling for me.
i could survive without my iPod and my television and the internet as these aren't really essential to life, i can last a day without going on the internet, i have lasted days and i'm sure lots of people in the past have. it's not important, the world seems to use it as some form of crutch to see if everyone in the world is exactly like them and to indulge themselves with no real purpose. yes everyone in the world is alarmingly similar and networking sites and friends are just a way of proving that unsuprisingly that as we all have have about 99.9% of the same DNA the rest of our free will is controlled by television and music and therefore we are all losing what identity we have by relying on entertainment and our own selfish minds to flourish with no true direction. our minute difference in DNA is slowly being drained away by the world around us... no one is different any more... ask a person this question and i have high suspicions that most would immediately say some form of entertainment they could not live with out. if there was no such thing as television i'm sure we'd get by, as well as if there was no such thing as the internet as the past million years have shown.

and don't get me started on iPods... it's another excuse to shut ourselves off from the world, a form of antisocial behaviour, a slight combination with self harm, blasting loud pulsing beats into your ears polluting the air around you with incorrigible premature deafness.

i can't live without soap. being clean is a million times better than being ignorant.
rant done.
