The task s of daily living that most of us take for granted are much more challenging to accomplish in outer space, especially those personal things involving an astronaut's privates. This question, how to capture human waste at zero Gs, is so important in fact, that in 2007 NASA spent 19 million to address it, purchasing a state-of-the-art toilet system for the international space station; quite a bit more cash than even the most extravagant powder room on earth would cost. {advcenter} Why Do Astronauts Need Special Toilets? With zero-gravity conditions in space, the toilet water, waste and user could not stay in place, but instead would float around weightless (Ewwwww!) When astronauts use the toilet, they must first strap in, just to remain sitting while doing their business. How Are Space Toilets Different from Earth Toilets? Without gravity, space toilets need to rely on suction (movement of air instead of water) to draw the waste into a holding container. The toilet bowl is for poop, and there must be a compete seal in order for the waste to move into the receptacle (Astronauts must get some serious toilet-seat rings on their fannies!) There is also cup with a seal and hose attached that both male and female astronauts can use as a urinal. What if Astronauts Need to Go During a Spacewalk?!? During the most recent mission of Space Shuttle Atlantis, Hubble Service Mission 4, astronauts had to complete five spacewalks in order to make the needed repairs and upgrades to Hubble. Most of those specewalks were seven hours or more, so you may wonder, "What if an astronaut has to poop or pee while on the job? The answer to this one is pretty low-tech. They wear diapers. NASA, of course, doesn't call them diapers. That wouldn't be technical enough. Instead, an astronaut's nappy is called a MAG (maximum absorption garment).

Nicotine is an ingredient that is mainly used in making tobacco products. It is highly addictive in nature. It occurs naturally in tobacco. Nicotine is a poisonous, yellow and oily substance which on exposure turns brown. As per a research it is said that approximately 3mg of nicotine is inhaled per cigarette. One can only imagine the bad it can do to our health, but instead, cigarette smoking has been attaining popularity since years now. A number of people indulging in smoking have successively increased from many years. Now not only men but even women and teenagers are addicted to cigarettes and cigars. Cigarette smoking has become the ‘in thing’ and a matter of pride. It’s a new fashion statement and trend that represents smoking to be the cool thing. Nicotine creates pleasant feeling in the smoker. It addicts a smoker physiologically. A smoker seeks for cigarette when in stress, happy or tensed moments. Smoking changes the world of individuals. To cut down on one’s loneliness or tensions related to office/ work, cigarettes seem to the smokers as the best option to reduce problems. While some carry on smoking as it has become a part of their lives, some wish to quit smoking but are unable to do so. These sects of people in fact do try their own ways of giving up smoking. The only solution they find is sudden quitting of smoking. Some may succeed though thanks to their strong will power, but majority of the times individuals find it very difficult to survive, as their body tremors and they feel weak from within and their capacity to think too diminishes. This drastic change makes it difficult for the people to survive, thus drawing them back to smoking.
