Average life expectancy has been on the rise yearly, from around the 40’s back in the 1900s, to almost 80 this year. So what brings this longevity? Effectively, we are only in poor health much later in our life. Access to health services, health literacy and a decrease in smoking nationwide, all plays a part in making our life so much longer. Nowadays, causes of death are less likely caused by parasitic and infectious diseases (the black plague for example) due to a much better sanitary practice and the existence of toilets. Death is likely to be caused by chronic conditions and non-communicable diseases (cancer, diabetes etc.). Then there is also the movement for immunization, millions are immunized against harmful strains, the likes of polio and the main childhood killer, measles.
