In 1950, global average life expectancy at birth was only 46. By 2015, it had shot up to over 71.

In some countries, progress has not always been smooth. Disease, epidemics and unexpected events are a reminder that ever-longer lives are not a given.

In 1990, one in three deaths resulted from communicable and infectious diseases; by 2017 this had fallen to one in five.

Child deaths in rich countries are now relatively rare, while the poorest regions today have child mortality rates similar to the UK and Sweden in the first half of the 20th Century, and are continuing to catch up.

Road accidents incur a high death toll in the richest and poorest countries alike, claiming 1.2 million lives in 2017.

These are some types of deaths which some are deadly and some could be really painful. Cancers=16.3%, Diabetes=5.8%, Dementia=4.4%, Road injurys=2.5% and Liver disease=2.3%.
