How Long May We Live?
People today live longer lives thantheir predecessors. Namely, while the American Colonists had themajority of individuals never reaching the age of 25, today,Americans are known to reach the life span of 78.1 years, on average.
Therefore, we are all living longer asthe years go by and our civilization advances in many respects. Thisall started with the development of the Industrial Era, when healthservices began to evolve seriously. Basically, life expectancy of anation depends greatly on the health service it provides to itspeople. So, the more advanced a country is and the more available itsmedical services are to its people, the healthier the people will beand the longer they will live. This simple equation leads us to thelife expectancy state of today, where people get to see parts of lifetheir forefathers could not have imagined.
Human Life Expectancy
The very definition of human lifeexpectancy as a term has ambivalent meaning. Firstly, it stands foran individual's life predictions, where we speculate upon thelongevity of this person's existence. Secondly, on a more wider scale,human life expectancy is a term used for the average age a group ofnewborn people reach, compared to the previously traced mortalityrates of the generations before them.
These rates are different amongdifferent societies and are influenced by many factors such asgender, health, social and geographic factors etc.
Simply, in countries where people haveto pay for their health expenses, they live shorter lives since theyoften wait for their symptoms to become serious or, even, severe. Onthe other hand, people who live in Canada, Norway, Sweden, Denmarkand many other countries which take good care of the health of theirpeople, live much longer lives than, for example, people indeveloping countries.
Moreover, in countries where peoplelive less, mortality rates of infants are higher as well. Taking intoconsideration that this factor influences the whole calculation ofhuman life expectancy in a country, the very calculations maysometimes lack precision since these factors are hard to track.
Clearly, wars, diseases, terribleliving conditions, famine and other such negative factors contributeto the shortness of life expectancy in certain areas. Gender,climate, economic statuses and working conditions are veryinfluential as well. Naturally, a business manager will live longerthan a coal miner, in most of the cases. Also, factors like geneticdisorders, mental illnesses, drug usage, alcohol and tobaccoconsumption are taken into consideration too.
Insurance companies benefit greatlyfrom these life expectancy lists, since they have a greater insightinto the future of their investments.
