Even though there are jillions of bacteria and viruses everywhere in and around us, only a small % are harmful to us. Our bodies have a self defense immune mechanism that recognizes the bad guys and is on watch 24/7 looking for the bad guys. When it detects one it springs into action building a defense or destroying the threat. However, sometimes it gets overwhelmed and the bad bacteria and viruses get the upper hand. The body needs help with things like antibiotics if it's not going to succumb.
In short, we have a department of defense that keeps us protected most of the time by killing bodily invaders.

That ? actually kix a--. Fact: your immune system greatly if not totally is influenced by your pedominant mood, nature ect. Did you know that people who have clinical depression have weaker immune systems. Also if you fear the flu\ common cold you are more likely to get it and not even the flu shot will help you out of this one.Finally if you make it a point periodically to declare to yourself with confidence that you are above illness you will remain healthy.I am 42 I do not take any drugs, aspirin ect I drink occasionally, smoked for the last 24 years and I eat only the best foods ,like fried chicken, pizza, french fries and mass quantities of chocolate cake but I workout every day, ( hit my heavy bag for 1 hour without a rest) and I have not even had the sniffles in the past 20 years.There is a a book called making miracles, it is a case study of 11 people who were diagnosed terminal but survived and not all of these people were religious, there is also a book called " Anatomy of an illness" it is the true story of Norman Cousins who beat a terminal heart condition basically through laughter. THE GRAND FINALE: The awsome Jesus even said " physician heal thy self". Peace

even though we are surrounded by bacteria and viruses, our bodies are built to resist them. From physical barriers like skin to the immune system response we are designed to fend off germs.
The human body is a pretty amazing thing.

We have a symbiotic relationship with most bacteria.We need each other to live.We become sick when there is an imbalance in the conditions necessary for our mutual normal growth.

because we have an immune system....a lot of bacteria we actually consume when we eat.....there are everyday bacterias that we come in contact with that our bodies have an immunity to

got news for you: we evolved with an immune system to protect us. remember life started with one bacteria-like cell, and from day one it had to cope with other cells.
it's a bit as if you said, this country has been at war against various armies over all of its history, and it still thrives, i'm surprised that it has an army and that this army functions so well. it's a "duh" moment ;-)
hope this helps

well, not only do we have an immune system as everyone's stated, the vast majority of of microbes are not actually pathogenic (they don't cause a disease in humans).
