world's wealthiest populations from around 50 to over 75 years.

This increase can be attributed to a number of factors including improvements in public health, nutrition and medicine. Vaccinations and antibiotics greatly reduced deaths in childhood, health and safety in manual workplaces improved and fewer people smoked. As a result of this - coupled with a decline in the fertility rate (the average number of children that women have in their lifetime) - many major industrial countries are facing an ageing population.

countries will continue to slowly advance and then reach a

peak in the range of the mid-80s. According to UN statistics for the period 2005 - 2010, Japan (82.6 years) has the world's highest life expectancy followed by Hong Kong (82.2 years) and Iceland (81.8 years). The world average is 67.2 years and the UK average is 79.4 years.

a child reaches their first year, their chances of living

longer increase. By the time of late adulthood, your chances of survival to a very old age are quite good. For example, although the life expectancy from birth for all people in the United States is 77.7 years, those who live to age 65 will have an average of almost 18 additional years left to live, making their life expectancy almost 83 years. Are we now more informed about how to prolong our lives?

since the nineteenth and early twentieth centuries. However, another important

factor is our knowledge of their importance to our health and life expectancy, and of the steps we can take to ensure that we lead a healthy lifestyle. Our access to relevant information has also improved dramatically as a result of scientific research and methods of information dissemination, for example the Internet.

The importance of eating a balanced diet is widely known Government and charity websites provide information about the lifestyle choices we can make in order to reduce our risk of developing diseases. The effect that smoking cigarettes can have on our health is widely advertised, and warnings included on packaging. In the UK, a smoking ban in public places has been introduced and the age at which young people can buy cigarettes has been raised to 18 years 2.Adverts on buses and tubes inform us of the importance of washing our hands and covering our mouths when we cough or sneeze in order to reduce the spread of illnesses and diseases.

Food, health and hygiene: The key to longer life

We are now going to focus on the ‘big three' reasons why people in the UK live longer lives that the used to before the industrial age.

categorise them as food, health or hygiene breakthroughs (some might

overlap slightly, just put them in both categories).

1.Are there any other facts not mentioned here that you have (i) learned in other subjects (ii) acquired as general knowledge (iii) gained through personal experience (e.g. vaccination jabs or knowledge of local health/ hygiene facilities and infrastructure) (iv) gained from watching this National Geographic film about Sardinians, Adventists and Okinawans.

2.You are now going to write a 'risk diary' using the risk diary template. For the next few weeks, keep notes detailing how protected your own life is. You may walk through a fire door or use a level crossing, spot a health warning on a product you use or look at the calorie and fat content on the printed label of the food you eat. Do you fasten your seat-belt or ‘stand behind the yellow line' as a train approaches?
3.Try to record as many possible instances when you become aware of being subject to rules or advice designed to help you stay healthy and alive.
