Average height over time

As we age we shrink in height, but I was curious as to the Average height for men over time and when I found this information I thought I would share it.

In 2010, the average American man was 69.3 inches. A century ago, the average American man was 67 inches. Though this marks a growth of more than 2 inches, the rate at which Americans are growing has actually slowed relative to other nations.

In 1896, American men were the third tallest in the world. Since then, they've slid to 37th place in height. This is not because Americans are shrinking; it is because other nations are growing at a more rapid rate while American height growth is slowing.

American heights have stabilized over the past 50 years. Every 20 years, Americans gained about 2 inches on their parents, but today's children will average the same height as their parents. This is largely due to better health and nutrition.

Over the last decades, American children have faced fewer growth-stunting nutritional problems or health issues, and so they have grown taller. Because this improvement in health has persisted for the last 20 years or so, children are no longer growing taller than their parents.

A study published in eLife reports that those nations that have experienced more significant improvements in health and nutrition have also grown taller.

East Asians have seen significant height gains over the last century. Iranian men have grown more than any other men, with height increases averaging 6 inches in this time. In Sub-Saharan Africa, poor nutrition has stunted growth, reversing gains in height over the last 2 decades.

Men born in the Netherlands are the tallest, with heights averaging just under 72 inches. Eastern European men also rank near the top of the list.

Indonesian men are the shortest, with average heights of 62.25 inches. Men from Malawi are a close second, with an average height of just 63 inches. Yemen, Laos, and Madagascar also have some of the shortest men.

In Britain and Australia, men average 70 inches tall. In France, the average man is 69.5 inches. In most cases, female height tracks male height, such that nations with taller men also have taller women.

Women in Guatemala and the Philippines are among the world's shortest, with average heights of 58 inches.

Factors that influence height
Height is 60-80 percent heritable, which means that 60-80 percent of the difference in height between people is due to genetic factors. This suggests that genetics influences the height differences between individuals living in environments that offer quality nutrition and little exposure to disease.

In more challenging conditions, factors such as diet and exposure to disease can significantly affect height.

Factors other than genetics that can affect height include, geographic location, and birth weight.

Birth weight: Birth weight is the result of many factors, including genetics and nutrition in the womb. It is a significant predictor of height.

Being born prematurely: Premature babies tend to have a lower birth weight, and prematurity is also an independent factor affecting height. Premature babies may grow into shorter adults.

Hormones: Hormones affect growth throughout life, and especially during puberty. Hormonal imbalances can make people unusually tall or short.

Nutrition: Nutrition is a major factor in height. Individuals who have poor nutrition, especially those who do not get enough calcium, vitamin D, and other vitamins and minerals, may not grow as tall.

Geographic Location: There is a significant relationship between geographic location and ethnicity, which is related to height. Beyond this factor, location affects exposure to natural sunlight, a source of vitamin D. Location can also affect access to healthful food, poverty, and overall health.

Stunted growth: Factors that stunt growth, such as eating disorders, severe illnesses, and exposure to some medications, can cause people to grow less tall than they otherwise would.

Weight and height: How they are related and why it matters
Weight and height are connected in terms of health. A healthy body mass index (BMI) involves a greater weight as height increases. This means that one person could be considered severely obese and another could be seriously underweight if they had substantially different heights while weighing the same.

A healthy BMI ranges from 18.5 to 24.9. BMIs between 25 and 29.9 are considered overweight, while a BMI above 30 indicates obesity. A BMI below 18.5 is considered underweight.

For an average man with a height of 69 inches, a healthy weight is between 128-168 pounds.

People with BMIs that are too low or too high are vulnerable to a wide range of medical conditions, including cardiovascular disease, diabetes, and metabolic syndromes.

Be the person you dreamed you be today

Sometimes I think it is just a matter of switching gears, never looking back, and being the person today that you've always dreamed you'd be.

Entertain every thought, say every word, and make every decision from their point of view. Walk the way they would walk, dress the way they would dress, and spend your free time the way they would spend theirs. Choose the friends they would choose, eat the meals they would eat, and love and appreciate yourself the way they would.

After all, that person is who you really are so why not be them now

Do you understand the role Vitamin B12 plays in your body?

I never understood the importance of B12 until a friend of mine was told he needed a B12 Shot. So, I did some research, here is what I found, and I thought it was interesting to share. Vitamin B12 is an essential water-soluble vitamin that plays an important role in many functions in the body, including:

DNA synthesis
energy production
nerve cell health
red blood cell formation
neurological function

B12 is present in many food sources (mainly animal-based), where it is bound to the protein molecules in that food.

Vitamin B12 is separated from the protein during digestion and is absorbed into the bloodstream.

Adequate stomach acid is required to release the vitamin from the protein, and a substance called intrinsic factor is necessary to ensure its absorption.

People who are unable to absorb vitamin B12 properly may have pernicious anemia, which is a type of anemia characterized by a lack of intrinsic factor.

The average daily intake of vitamin B12 is 2.4 micrograms (mcg) for men and women over 14. Pregnant and breastfeeding women require slightly more, at 2.6 mcg and 2.8 mcg, respectively.

People with signs and symptoms of B12 deficiency
Anyone who is displaying any of the signs and symptoms of a B12 deficiency or pernicious anemia should consult their doctor immediately.

Some common signs and symptoms include:
decreased cognitive function, such as issues with memory or understanding
fatigue
lethargy
constipation
feeling faint
depression or irritability
headache
difficulty maintaining balance
sore, swollen tongue, which may be pale yellow or very red
heart palpitations
mouth ulcers
paraesthesia (pins and needles)
vision changes

B12 and Older Adults
Research suggests that vitamin B12 deficiency affects a greater number of older adults than those under the age of 65.

Older adults can be affected by conditions that are linked to a decrease in stomach acid production, including inflammation in the stomach (atrophic gastritis).

Furthermore, lower levels of stomach acid can encourage the growth of certain bacteria in the gut that uses B12, reducing the amount of the vitamin available to the body.

The Institute of Medicine recommends that adults over 50 meet their vitamin B12 needs with fortified foods, B12 shots, or other supplements, as these man-made forms appear to be more readily absorbed than naturally occurring B12.

B12 deficiency risk factors
Both diabetes and some medications for type 2 diabetes can increase the risk of vitamin B12 deficiency.
Also, the following risk factors can increase the chance of developing vitamin B12 deficiency:

alcohol abuse
smoking
certain prescription medications, including antacids and some type 2 diabetes drugs
having an endocrine-related autoimmune disorder, such as diabetes or a thyroid disorder
eating a vegetarian or vegan diet
certain gastrointestinal disorders, such as Crohn's disease
gastric bypass or the removal of parts of the stomach
aging

Drug interactions
Never start, stop or change your supplement routine, without checking you’re your doctor. Vitamin B12 may interact with certain medications. People must always inform their doctor about all prescription and over-the-counter drugs they are taking before receiving a B12 shot.

Some commonly prescribed medications that may interact with B12 include:

Aspirin
antibiotics
H2 receptor antagonists
metformin
oral contraceptives
proton pump inhibitors

Allergy and medical conditions
Those who have allergies or medical conditions should always inform their doctor before receiving a B12 shot. Examples of allergies or conditions that may interact with B12 shots include:

allergy to cyanocobalamin or cobalt
hypokalemia (low potassium levels)
kidney disease
polycythemia vera (a rare blood disorder)
Leber's disease (an eye disease)
deficiencies in other nutrients, particularly folic acid and iron

There are several reasons to consider getting a B12 shot, including:

Reduced risk of vitamin B12 deficiency and associated complications

The most obvious benefit of receiving vitamin B12 shots is treating a vitamin B12 deficiency and avoiding its associated symptoms.

In addition, B12 shots reduce the risk of some serious complications associated with vitamin B12 deficiency including:

heart disease
neurocognitive disorders
coordination problems (ataxia)
peripheral neuropathy
vision loss
infertility (although this usually resolves with B12 treatment)
neural tube defects in the babies of women with B12 deficiency
High levels of assimilation by the body

Lack of empathy shows

In Britain, more than two million women born in the Fifties face having to work an extra six years before retiring after changes to their retirement age. Governments faced with decades of lack of planning and understanding of the issues facing them as Boomers get older are making bad decisions.  Many of our governments have a short term horizon, and they only see until the next election or not even that far. 

The recent changes in Britain have caused many problems and when asked about the fact many women will have to work an extra six years, a  Minister of the Crown said: “The reality is over 200,000 people over 60 have entered further education since 2014/15.

“We have also extended apprenticeship opportunities as one of the best routes to skilled employment for people of all ages and gender.”
The comments in a heated Westminster Hall debate triggered shouts of “Shame on You” from Labour and SNP MPs.
Campaigners slated the government for trying to push “Grannyships”.
Taking to social media, One woman wrote: “I’m 62, can I be a bricklayer?”
An outraged Old Age Pensioner added: ‘Perhaps I could have an apprenticeship as a hairdresser in a modern salon at the age of 64? I don’t think so.”
The Waspi Women – Women Against State Pension Inequality – want transitional arrangements put in place to help them after seeing their pension age rise from 60 to 66.
The increase follows two changes to the retirement age, one in 1995 and the other during the Coalition.  In my mind, the issue is not the change, but the speed of the change. 
Research shows that people do not start to plan for retirement until they are in their early to mid-fifties, and if the rules change without adequate warning then people become angry and stressed. The changes in  Britain were done to save money and without consultation or warning. 
As Boomers age around the world, there may be more of these dumb decisions by governments as they try to come to grips with decades of no or poor planning. As individuals, it becomes important to understand that the government will not be there for us when we retire, and we need to start our own planning and saving. The sooner the better.
