However, it seems there should be more that affect life expectancy that I would love to know. Let's discuss.
The world we live in today, I believe, is the primary cause of lower life expectancy. People lived up to 500 years centuries ago and were still fully healthy and active for farm labour and other recreational activities. But everything has changed today, and the environment we live in is no longer natural, but artificial. Many modern developments have forced the green environment to flee, and all of this is hurting the natural habitat environment. This has lead to a shorter life span and has had an impact on our earth, animals, and humans. We may be unable to live without these inventions because we were born with them, but it is now expected that we will not have a longer life expectancy.
