Both of these are a means of expelling germs out of the body, right? So, why do we do both instead of just one of them?

Coughing serves the dual purpose of eliminating foreign particles from the wind pipe&lungs as well as preventing choking when the food we eat by mistake enters the windpipe instead of the foodpipe.\n\nSNEEZING on the other hand is just the body's way of throwing out foreign particles which have entered the nasal passage.

I spend a lot of time in elementary schools.  It's not bad for fighting germs picked up from door knobs etc. but I have heard that it can make it harder for you to fight off infections because  you're killing all the germs so your body can't build up tolerance.\nIt can also dry your hands out.  But I say keep on using who knows what others have on their hand.

One reason is the professional look, I get many compliments on my uniform(it does look rather sharp), the other reason is it is easier to see where we may have contamination on our clothes,(mucous,blood, urine, stool, ect)this allows us to change our clothes to minimize passing along pathogens. There is a sign that hangs by our sink, it says, "Have you ever killed a man with your bare hands?...Are you sure?" as a nurse we need to constantly be washing our hands and the white shows other areas that may be contaminated.

we close our eyes to keep them safe from debree and germs eg when you sneeze you automatically close your eyes this is a message from your brain to your eyes telling them that you have sneezed so to keep them closed from germs when you blink it alsokeeps your eyes moisterised \n\ntry to keep your eyes open when you sneeze

It has been proven over and over again that regular handwashing can result in a healthier lifestyle.\n\nHandwashing Keeps Us Healthy \nHERE'S WHY!\n\nBacteria and viruses that make people sick can be passed on our hands. Handwashing is the most important way to reduce the spread of infection. You can't avoid collecting germs, but you can reduce the chance of infecting others by knowing when to wash.

To protect us from their germs and bad breath, and to protect themselves from ours.

Neither one is 100% guaranteed, so if you are going to be having sex and don't want to get pregnant, it would be a good idea to use both!

B ...\n\nWe Sasquatch have realized that most germs which cause health problems reside on the hands.  Thus, washing the hands on a regular basis is benificial and healthy!\n\nNot only because you often pick up food with your hands, but also because one often touches their nose, mouth and ears several times a day (as well as other body parts)!  Germs are part of our everyday life and therefore, we need to wash our hands regularly!\n\nIMHO,\n\nThe Ol' Sasquatch Ü

I've heard that.  It must of been on TV or something because several guys came to work talking about it.  Something about the bacteria strengthening your immune system.\n\nI'd rather get sick.

It's a reflex, a defence mechanism, in order to protect your lungs from taking in foul air for too long and polluting the air circulation system inside you! And then, also to protect your stomach from foul intake, as the smell induces puking and prevents you from eating the foul stuff! The Brain 'impressions' and the Mind reflexes together work towards safeguarding the Biology in you!

As sticky as chewing gum might appear to be outside the body, once it's sent down the alimentary canal it's no more remarkable in that respect than most anything else we swallow.\n\nGum is eliminated as human waste in the same way — and at the same rate — as any other swallowed matter. Granted, it comes out the far end relatively unchanged by the trip, but it does come out on schedule.

This would not be possilbe.  In the process of digesting and assimilating these essential elements, our bodies create some waste or by-products.  We have to get rid of it somehow.\n\nOur bodies are not Carnot engines - we cannot attain 100% efficiency.  The second law of thermodynamics tells us this (entropy is increasing).\n\nPlus, there are very few pleasures as great as sitting down and passing a nice well-formed turd.

It seems self-explanatory. There is a price to be paid for everything, including the breath we take. Did you know that one reason for cell-degeneration (namely aging) is because we are oxygen-breathers? Oxygen causes us to 'rust' in pretty much the same way it does iron and other metals. So, even the breath we take is not free, we pay for it with every cell that dies.

why cant we have both?

I actually had a pediatrician tell me that when you have a child with congestion, you can firmly pat their back and have them cough at the same time to loosen any phlegm or mucous that may be in the lungs or obstructing an airway; maybe this Argentinian was just a lot more forceful, if it was indeed a life or death situation.

One is a toilet, and one is a bidet. A bidet shoots a stream of water into that delicate place to get it super-clean.

it used to be isolate the pathogen from an infected host and use it to infect a healthy animal, but i believe they are now using the third choice more because the second choice doesn't always work.  so i would say isolate bacterial/viral proteins by electrophoresis.
