To understand the what happens in an entire country it might be enough to consider what happens to the life expectancy of just one person who has access to safe water or improved sanitation.
First, what is life expectancy? The life expectancy for a person is calculated by adding up the products of all ages that the person might achieve and the probabilities that the person might achieve those ages. Let's assume that no-one lives beyond, say, 100, and that we are willing to ignore ages in months. Then we have ages, 1, 2, 3, 4, 5, 6, ..., 100. In some countries, most unfortunately, the probability of living to age 6 might be only 0.5 so the product for this age would be 6 * 0.5 = 3. The probability of living to age 10 might be only 0.2, so the product would be 10 * 0.2 = 0.02. We would calculate these products for each of the 100 ages and add them, then divide by 100, to obtain the life expectancy
Now, with access to safe water a child would be far less likely to die before age 10. In other words that probability of survival of 0.2 would be considerably larger, say, 0.7, and the corresponding product would be larger. Simply put, the person would live longer because he would be less likely to be killed by some disease transmitted in unsafe water. In fact, unsafe water is a hazard to people at all ages; therefore, the probabilities used in those products would be somewhat bigger for all ages. The idea is the same for improved sanitation.
Keeping faces and hands clean may help break the cycle of reinfection. Improved access to water. Fly control. Reducing fly populations can help eliminate a source of transmission.
The verb forms are access, accesses, accessing, accessed. The verb access is an action verb (a verb for an act).
No, it is an adjective. It is related to the noun access and the verb "to access."

Environmental factors that can affect life expectancy include air quality, access to clean water and sanitation, exposure to hazardous substances, availability of healthcare services, and the overall socioeconomic conditions of the area. Additionally, climate-related factors such as extreme temperatures and natural disasters can also impact life expectancy. These environmental factors can contribute to various health issues and increase the risk of diseases and mortality.
people had no access to medicine and sanitation was not used at all
Life expectancy is theoretical and death rate is a real measurement. life expectancy can be used to predict the death rate if you know the average age of a population.Although the previous answer above is true, it does not answer the question. Life expectancy affects death rate as if the life expectancy is high, like it is in many High Income Countries (HIC's), the death rate is higher, because aging populations will inevitably have rising death rates as older people are more likely to die, than younger people.//Saying this, if the life expectancy is low, then often the death rate is high (like in many LIC's) as this is a result of poor medical care (or access), lack of clean drinking water and poor sanitation.\\
UNICEF works in more than 100 countries to improve access to safe water and sanitation facilities. But 768 million peoples are still with impure drinking water.

Water supply and sanitation in Tanzania is characterised by: decreasing access to Improved_water_sourcein the 2000s (especially in urban areas), steady access to some form of sanitation (around 93% since the 1990s), intermittent water supply and generally low quality of service.
Some 1.1 billion people in developing countries have inadequate access to water, and 2.6 billion lack basic sanitation.

The life expectancy for women in the 1930s was around 64-65 years. However, it is important to note that this is an average and individual life expectancy could vary depending on various factors such as socioeconomic status, access to healthcare, and lifestyle.

There is no definitive answer to this question as life expectancy can vary greatly based on various demographic, socioeconomic, and lifestyle factors. It is important to note that sexual orientation alone does not determine life expectancy. Overall, factors such as access to healthcare, socioeconomic status, and lifestyle choices can have a greater impact on life expectancy.
