    You breathe everyday. You can't even take a rest from breathing. It's so weird.

    Good luck. There's a scientific explanation for everything. It is scientifically possible to stop breathing, although breath would be short.

    I find breathing pretty fun :P it reminds me that I'm still alive haha.

    We can't take a rest from breathing because we will die! It's not really weird, just how to human body flows well.

    Well I read the Wikipedia article, Kristine. I am surprised that you read that kind of scientific nonsense. Take this for example,

    Carbon dioxide (chemical formula CO2) is a naturally occurring chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas at standard temperature and pressure and exists in Earth's atmosphere in this state, as a trace gas at a concentration of 0.039% by volume.
    As part of the carbon cycle known as photosynthesis, plants, algae, and cyanobacteria absorb carbon dioxide, light, and water to produce carbohydrate energy for themselves and oxygen as a waste product.[1] But in darkness photosynthesis cannot occur, and during the resultant respiration small amounts of carbon dioxide are produced.[2] Carbon dioxide is also produced by combustion of coal or hydrocarbons, the fermentation of liquids and the breathing of humans and animals. In addition it is emitted from volcanoes, hot springs, geysers and other places where the earths crust is thin; and is freed from carbonate rocks by dissolution. CO2 is also found in lakes at depth under the sea, and commingled with oil and gas deposits.[3]
    The environmental effects of carbon dioxide are of significant interest. In the earth's atmosphere, it acts as a greenhouse gas which is believed to play a major role in global warming and anthropogenic climate change. Also a major source of ocean acidification is CO2 which dissolves in water forming carbonic acid,[4] which is a weak acid, because CO2 molecule ionization in water is incomplete.
    CO2 + H2O H2CO3

    WTF???? :O

    Kirby, that "scientific nonsense" is actually quite interesting and fascinating stuff to learn. The reason why we can't really get a break from breathing is:
    Being diprotic, carbonic acid has two acid dissociation constants, the first one for the dissociation into the bicarbonate (also called hydrogen carbonate) ion (HCO3):
    H2CO3 HCO3 + H+
    Ka1 = 2.5104 ; pKa1 = 3.6 at 25 C.[5]
    At high pH, the bicarbonate ion dissociates significantly into the carbonate ion (CO32):
    HCO3 CO32 + H+
    Ka2 = 4.691011 ; pKa2 = 10.329

    sorry kristine, but i must say...
    WHAT....THE.....f---!!!!!!!

    We're not finished yet explaining! The chemical reactions also play a major role for the society of our breathing. Overall, CO2 is a weak electrophile. Its reaction with basic water illustrates this property, in which case hydroxide is the nucleophile. Other nucleophiles react as well. For example, carbanions as provided by Grignard reagents and organolithium compounds react with CO2 to give carboxylates:
    MR + CO2 RCO2M (where M = Li or MgBr and R = alkyl or aryl).
    In metal carbon dioxide complexes, CO2 serves as a ligand, which can facilitate the conversion of CO2 to other chemicals.[6]
    The reduction of CO2 to CO is ordinarily a difficult and slow reaction:
    CO2 + 2 e- + 2H+ CO + H2O

    Kristine...
    are you alright in the head? *knocks on your head* Hm... as hard as a nutshell.

    Sophia, it's not complicated. Trust me. Very easy once you become competent with it. Rational skills of the head.

    Anyway, I'm not finished yet. I need to explain more for it to summarize.
    So, back to our sums.
    CH4+ 2 O2 CO2+ 2 H2O
    The production of quicklime (CaO), a compound that enjoys widespread use, involves the heating (calcining) of limestone at about 850 C:
    CaCO3 CaO + CO2
    Iron is reduced from its oxides with coke in a blast furnace, producing pig iron and carbon dioxide:[13]
    Fe2O3+ 3 CO 2 Fe + 3 CO2
    Yeast metabolizes sugar to produce carbon dioxide and ethanol, also known as alcohol, in the production of wines, beers and other spirits, but also in the production of bioethanol:
    C6H12O6 2 CO2+ 2 C2H5OH
    All aerobic organisms produce CO2 when they oxidize carbohydrates, fatty acids, and proteins in the mitochondria of cells. The large number of reactions involved are exceedingly complex and not described easily. Refer to (cellular respiration, anaerobic respiration and photosynthesis). The equation for the respiration of glucose and other monosachharides is:
    C6H12O6 + 6 O2 6 CO2 + 6 H2O
    Photoautotrophs (i.e. plants, cyanobacteria) use another modus operandi: Plants absorb CO2 from the air, and, together with water, react it to form carbohydrates:
    nCO2 + nH2O (CH2O)n + nO2
