Non-specific defence can be further categorised into external (preventive) or internal (defensive). Innate defence can be physical‚ chemical or biological. The skin‚ commensal organisms (e.g. bacteria)‚ mucous membranes and hair contribute to the physical mechanism of the body’s non-specific defence against disease.

The ageing future Since 1950‚ the world’s population has almost tripled. All of us are living longer than any generation in human history In the year 2000 there were 100‚000 people around the planet who were 100 years old or more. Yet‚ when they were born‚ before aeroplanes and antibiotics and atom bombs‚ before cars and computers‚ there were very few centenarians anywhere in the world. Now millions of people will live into their 70s‚ 80s‚ and 90s‚ and centenarians will no longer be rare. Advances

In 1970‚ the population Pyramid shows that Oman was LEDC (low economically developed country) due to the high birthrate and low deathrate (triangular pyramid). There are number of reasons for high birthrate at that time. First of all‚ the religious reasons have affected the country to have high birthrate. The Omani culture at that time used to have many children for families so they have a great prestige and standing in society. Secondly‚ because Oman was not very developed at that time‚ the country

Many people (including national leaders) worry that population growth depletes resources and can trigger social or economic catastrophe if it is not contained. As discussed in the preceding section‚ most of the projected population growth during this century will take place in developing nations. These countries have faced many challenges in recent decades‚ including low levels of education‚ poor health standards‚ poverty‚ scarce housing‚ natural resource depletion‚ wars‚ and economic and political
