Before you go into panic, know that when talking about human life span the numbers take everyone into account. Developing countries, war victims, diseases, car accidents, tobacco and alcohol, suicides and so on. All these things lower the actual average. This is harsh, but countries with high percentage of Infant deaths really mess up the statistics for that country. The real average of a modern country is closer to 80. 88 if you're a Hong Kong female. If you take care of yourself, have a bit of luck and live long enough to die from old age, you are likely to be well over 90 years old. You see, the average is just that. The average. Half of the population will live past it.

We as humans used to live past 900 years, but thanks to the imbecility of some humans calling themselves intellects and thinking themselves wiser; created fossil fuel consumption machines and food preservatives with an honorable mention of nuclear fission, fusion technological devices that can wipe out cities of 350k ppl or more in 8 seconds. Now we can live a meager 80 years if things are savvy and we ignore society and go live in the countryside. Unless you're Japanese and grew up in the 70s and walked for a living, and ignored white people's ramblings on how to live a healthier lifestyle then you can live to 100+

When prehistoric humans still were hunter-gathers, the average human baby grew a lot faster than one does today. It didn't have the luxury of being completely helpless for years. So a one year old in those times would be the size of the three year old today. So I'm sure prehistoric humans might have had a very short life span, because they grew (and I guess also aged) more rapidly. (I'm referring to the early human who was lucky enough to die a natural death. Not one who would've died of poisoning, animal attack, illness, or severe injury)

Genetics play a definite role in longevity. In spite of the fact that our knowledge of our body, nutrition and diseases has grown so much, we are still not living significantly longer. The increase in average lifespan can be attributed to better nutrition and healthcare. We need to figure out the genes responsible for cell division failure and a way to splice it out of us.

Breathing pattern also plays an important role. Like turtles breath slowly so die slowly and monkey or dogs breath faster causing less life span. Humans can also increase their life span by controlling their breathing pattern. In India, we have lot of techniques for breathing (called Pranayam. Search about it.

I am wondering what the evolutionary benefit is of having a short life span? The goal in the game of evolution is to have as much offspring as possible that also reproduces. Limiting your lifespan does not help in achieving this goal. Some creatures like lobsters can live forever, so why do we deteriorate?

i would dare say longer life expectancy in humans is due to medical advancement, to say nutrition has got to be a joke unless by nutrition you simply mean availability of food because it certainly isn't due to an overall healthier diet.

Thats cool and all but to explain the scientific reason for animal lifespan shouldnt involve being hunted as a factor, just how their bodies through their lifespan works to keep them alive on average based on each species

Two more factors for animals that have longer lifespans: no bills; no in-laws.
So rats & gnats must have those two things _not_ going for them.
This isn't helping me feel my age. I'm 49, but I feel 89.

I was hoping this was going to discuss why small breed dogs tend to live longer than large breeds because that's completely contrary to most other animals.
