Average Lifespan in U.S. | It's increasing

Did You Know?

In 1900 the average lifespan in the US was 47.

There is a lot of data that tells us about the quality of life of people throughout time. From forensic records and bone samples of people who live two thousand years ago to the dental records and death records of people who died just yesterday. What does that data tell us about the life expectancy of Adults in the US both from a century ago and today?

There are many factors that impact the life expectancy of people and individuals. War, disease, genetics, diet, lifestyle, gender, and health are a few of those. As we explore this data, ask yourself about your own health, wellness, and how they impact your own life expectancy. The short story here is that life expectancy is expanding and people are living longer than they once did. Here is a closer look at that progress.

In 1900, the expectation for white men was to live to age 47 and 12 percent of those born in 1900 would make it to age 65. In contrast, an African American man born in 1900 was only expected to live until the age of 33 and of those born in 1900, only 10 percent of them would live to reach age 65. For both white and African American men born in 1900, a mere four percent ( for each) would reach age 85. By 1910 the life expectancy for white men grew by two years and those born in 1910 the expectancy was to live to 49 years of age.

For African Americans, that decade saw only a single year improvement in life expectancy. Five percent of African American men born in 1910 would reach age 85, whereas, only four percent of white men born in that year would celebrate their 85th birthday. In 1920, white men had an expectancy to live to age 54 and African Americans to age 46. In the 1920's several medical breakthroughs occurred. We discovered things like vitamins, vaccines, and the introduction of new medications such as Sulfa – all helped to improve the life expectancy. At the end of the 1920's (1929) the great depression started. It would last until 1939 when another incident – World War II – would begin. Both of those events caused premature death. Despite all this, life expectancy in the 1930's rose for white men with an expectancy to live until the age of 60. For African American, the life expectancy for men was low – age 47.

For African American men born in 1930, a decrease in the data appears – only four percent would reach the age of 85. A drop of one percent. White men born in 1950 had a life expectancy of 67 – which today is the age of retirement. For African American men born in 1950, the life expectancy was 59 years of age – nearly a full decade earlier than that of white men. I fact, African American males have a life expectancy of age 68 only after the year 2000 and for white men, born in 2000, the life expectancy is age 75. A difference that parallels from 1950-2000. In part, the jump in life expectancy in 1950 were improvements in medicine, such as the development of the external pacemaker in 1952 and the first successful open heart surgery in 1953. Read more about the advancements in medicine as a timeline.

White women born in 1900 were expected to live until age 49 and of those women born in that decade, 12 percent would live to be age 65 and 4 percent to age 85. For African American women born in 1900, life was short. Their life expectancy was only 34 years and only 11 of those women would make it to age 65 and five percent would turn 85. For those women born in 1910, white women on average lived until age 52 and African American women to age 38. It would not be until the 1950's that African American women would live to reach age 63. In 1950, white women had a life expectancy of 72. For those women born in 1950, 15 percent would reach age 65 and five percent of white women would make it to their 85th birthdays and six percent of African American women would reach age 85. Between 1900 and 1950 only 12 percent of white women would live to reach age 65 and 11 percent of African American women would live to age 65. By the year 2000, White women had a life expectancy of 80 years and African American woman were expected to live to age 75.

What the data shows us that as technology improves and advancement in medicine and medical procedures improve, the life expectancy of men and women expand. Technological advancements, such as medical alert systems, have greatly contributed to increased life expectancy. Also, improved elder care found in nursing homes, convalescent homes, memory care facilities and assisted living facilities have all helped to improve the average life expectancy.

A good example of this is the Gregor Mendel's genetic experiment in 1866 – the first scientific description of genes and how they work. Today, we understand a fair bit more about genetics but there is much left to learn. As time passes, those people born today, well have a longer life expectancy than that of their parents. It is quite possible that as Americans, we could top the century mark for life expectancy for all men, women, and every heritage that calls the US home. What that means is that we must look to the future to make sure that we have in place the resources to meet our needs as we age. Those include savings, insurance, and a legal framework that helps us to enjoy the later years of our life, whatever our life expectancy should be.

SOME FACTS ABOUT OXYGEN! SHORT ESSAY

Did You Know? Oxygen is the most common element in the Earth's crust. The rigid, top layer of the Earth is called the lithosphere. It consists of the Earth's crust and the top-most part of the mantle. Most geological activities that affect the Earth take place on the lithosphere. It is the most rigid of all of Earth's layers. The lithosphere consists of oceanic and continental lithospheres. Oceanic lithosphere consists of Oceanic crust which forms the floors of seas and oceans while continental lithosphere consists of continental crust made of land masses. The Earth's crust is important as it supports human and plant life and contains elements and such as aluminum which facilitate technological development. The most abundant elements in the Earth's crust are presented below: Oxygen - 46.6% Oxygen is the most abundant element in the Earth's crust. Oxygen makes up 467,100 ppm (parts per million) of the Earth's crust, or 46.6%. It exists as a major compound of

Sneezing with Open Eyes

Did You Know? It's extremely hard to sneeze with your eyes open. Although you can focus to keep your eyes open when sneezing, your body's blinking response is likely there to protect itself from germs. The changing weather brings about many things: holiday excitement, a different wardrobe and -- perhaps most annoyingly -- cold and flu season. Those around you have likely been sneezing more frequently, which may have prompted you to ponder, perhaps while applying mascara or driving in bumper-to-bumper traffic, if it is possible to sneeze with your eyes open. David Huston, MD, associate dean of the Texas A&M College of Medicine Houston campus and an allergist at Houston Methodist Hospital, said it is "absolutely possible" to sneeze without closing the eyes, but most people tend to automatically close their eyes when sneezing. It is an autonomic reflex, which is an unconscious motor action in response to a stimulus: in this case, sneezing. "The fact that it

Article: Apple Watch Users Can Now Monitor How Bodies React To Coronavirus

Apple Watch has been lauded by most to be the best smartwatch out there. This is not only because of how well it works but also because of the sheer health and wellness features it brings to the table. Now, Cardiogram - a heart health application for Apple Watch - is introducing a new feature that will give users more information on how their body is responding to a COVID-19/flu. The new feature called Sleeping BPM revolves around how our body reacts while we're fighting an infection like COVID-19."Cardiogram's new Sleeping BPM feature can help users become more aware of how their body is responding to symptoms of the flu or other illnesses including COVID-19," said Johnson Hsieh, Cardiogram's co-founder to Apple Insider . He further went on to explain how this feature works. When we're sick, cells in our immune system release small proteins called histamines which cause inflammation and expansion of blood cells. This process sends signals to our brain to in

Cat Breeds

Did You Know? There are more than 40 cat breeds. The two largest organizations are the Cat Fanciers Association (CFA), which operates mostly in North America, and its European counterpart, Federation Internationale Feline (FIFe). CFA recognizes 45 cat breeds at present. The newest additions are the Khao Manee and Lykoi. Both allowed to compete in cat shows starting in 2018. FIFe recognizes 51 cat breeds. These differing numbers do not mean that FIFe recognizes five more breeds than CFA does. There are quite a few breeds that are unique to each organization; for example, the German Rex is one that FIFe acknowledges, while only the CFA recognizes the Ragamuffin. In general, Europeans seem to be more open to recognizing short- and long-haired versions as different breeds, such as long- and short-haired American curls and Selkirk Rexes, while the CFA says that these are two versions of the same breed. The total number of distinct breeds recognized by either or both the CFA and FIFe is 64.

Brain Connections

Did You Know? New brain connections are created every time you form a memory. People often compare the brain to a computer, but the brain doesn't have USB slots that allow you to pick up new information by jamming a flash drive in your ear. That would be convenient, if a little painful. So where do we get all this information sloshing around in our skulls? You might imagine human memory is a bit like a Santa's sack filled with life events, song lyrics and the first half of jokes. But in truth, "memory" is not one single solid thing. It is a term covering lots of types of recollections that are surprisingly distinct, and used constantly in different combinations by a typical human.

LIMIT OF RUNNING! IS HUMAN BETTER THAN OTHER ANIMALS?

Did You Know? Humans can outrun almost every animal on earth over long distances. When it comes to long distances, humans can outrun almost any animal. Because we cool by sweating rather than panting, we can stay cool at speeds and distances that would overheat other animals. On a hot day, a human could even outrun a horse in a 26.2-mile marathon.

Men vs Women Running | amazing facts

Did You Know? Because men's hearts are 20 - 25% larger than women's, especially the left ventricle, men can run longer and more easily than women. Men's hearts are 20-25% larger than women's, particularly in the left ventricle. This increases the ability to pump oxygenated blood around the body to be used in the muscles, making it easier for males to run faster for longer. The primary male hormone is testosterone, which stimulates muscle mass development. The female primary hormone is estrogen, which stimulates fat accumulation. Testosterone also increases the concentration of red blood cells, and hemoglobin, both critical for transporting oxygen around the body. This means that on average male blood can carry around 11% more oxygen than female blood to increase efficiency to run faster.

HORSE CAN SLEEP WHILE STANDING!

Horses first lived in the wild where their flight-or-fight instinct became very strong. As a result, sleeping standing up enabled the horse to flee quickly when danger was sensed. Lying down to sleep significantly reduced the horse's ability to run away fast. Do horses ever lie down and sleep? Yes! In fact, many horses prefer to sleep lying down than standing up simply because it is much more comfortable. It is not uncommon to see a herd of horses, many of them lying down, but with at least one standing up. The standing horse is keeping watch over the others, keeping eye on any potential predators or other signs of danger. HORSE When a horse is sleeping while standing they are not in a deep sleep, but are in a lighter sleep or snoozing. However, like humans, horses do need to have REM or rapid eye movement sleep that occurs during deep sleep. Also like humans, horses engage in slow-wave sleep (also known as SWS). To do this, the horse must lie down, not just with its legs tucked un

Tree Hugging in China
