Life Expectancy Factors

Life Expectancy Factors
Genesis 5:27 tells us that Methuselah lived for 969 years. While he is the champion of longevity, Genesis records all of the men of that time living hundreds of “years.” We put “years” in quotes because there has been a lot of speculation as to how a human can live that long–or whether any human would want to. There are many life expectancy factors to consider.

We have suggested that at the very early period in human history the definition of a year may have been very different from what it is today. Interestingly, other cultures such as Chinese, Egyptian, and Aztec recorded humans living hundreds or even thousands of years. We know that in some cases they based their year on the Moon or climatic factors, not the Sun. Those of us who have been blessed with very long lives know that the quality of life decreases logarithmically with age. As an octogenarian, I can tell you that living 969 years is something I would not want to experience.

Another question connected to this issue is whether the damage we do to ourselves with diet and recreational drugs accounts for some of this age issue. In The Week for May 4, 2018 (page 21) there are two interesting news reports. One is a study on Vox.com which reports that being a night owl produces a 10% greater risk of death than early risers The study also shows that chronic health issues such as diabetes, neurological disorders, and respiratory disease are more likely in night owls because they live in a perpetual state of jet lag.

In the same issue of The Week carried a report from Cambridge University showing that even moderate drinking of alcohol cuts years off a person’s life. Two or three drinks a day can cut up to two years off a person’s life. A study of 600,000 people reported on CNN.com lists eight major health hazards that come from moderate drinking.

How much can all of this do to shorten life expectancy? Probably not 900 years, but research is showing the effect of human indulgences in unwise lifestyles are greater life expectancy factors than anyone knew. When you add genetic issues to the equation, the idea of nomadic people who avoided the germ spreading environment of primitive cities is not as far-fetched as it appeared 25 years ago.

Becoming New Creatures

Becoming New Creatures
The National Geographic Channel has been airing a very interesting new series of programs titled “One Strange Rock.” The series hosted by actor/comedian Will Smith tells about the many “strange” and “lucky” features of planet Earth that make it possible for us to live here. In the most recent episode, eight astronauts explain why they think that humans should colonize space. They and some other prominent individuals have recently suggested that colonizing other planets or living in space may be the only hope for the human race to survive. In the process we might find ourselves becoming new creatures.

This episode brings out the many ways that space life will affect our bodies. Based on present experience with the International Space Station we know that bones and muscles weaken when they do not have to overcome the effects of gravity. Body fluids shift upwards causing other physical changes. There are changes to a person’s eyesight which can be permanent. Outside of Earth’s atmospheric protection, astronauts face greater amounts of cosmic radiation that can trigger “light flashes” in their eyes. Long exposure to the higher levels of radiation may lead to cancer or brain damage. At the same time, bacteria grow faster and can become more deadly in a zero-gravity environment. The environment of space, even with the best protective gear science can devise, may at best be toxic and at worst fatal to humans.

Even with those considerations, the astronauts are saying that we must colonize space. Part of their reasoning is that humans have evolved to handle the challenges of life on this planet, and we will perhaps evolve becoming new creatures to handle the new hazards of space. They say it will just be a matter of adapting to a new environment. Will Smith said in this episode, “Even if we survive the journey and make the place feel like home, we still might not save our species. Just by being there we might turn into something else.”

I think that the real answer to human survival IS for us to turn into something else. Human survival depends on people turning away from their sinful passions and hatred. It involves becoming what God created us to be and living out the teaching and example of Jesus. Going to another planet and taking along our sinful nature with all of its baggage will not save us. The real hope for the survival of the human race does not involve leaving the planet God created for us. It does not require leaving Earth with all of its “strange” and “lucky” features that make life possible. It is not necessary for us to go to a much more hostile environment and evolve into new creatures. The answer to our survival is becoming new creatures here and now as described in 2 Corinthians 5:17.

IQ and Intelligence

IQ and Intelligence
My first master’s degree was in psychometry, which is the study of tests and measurements. I worked under Dr. David Segel who was a pioneer in that field. One of the interesting things I learned in my studies was that IQ and intelligence are two different things. Many people use the terms interchangeably, but IQ (Intelligence Quotient) is a measure of your ability to perform on a certain kind of test. My mentally challenged son Tim scores very poorly on a Stanford Benet IQ test and very well on a Wechsler Bellevue IQ test. The Stanford Benet test measures an individual’s ability to manipulate and control shapes and spaces. The Wechsler Bellevue is a verbal test. The two tests measure different things, and Tim’s scores were wildly different depending on the type of test.

IQ and intelligence should not be confused. Webster’s dictionary defines intelligence as “the ability to learn and understand,” which has nothing to do with any test. IQ is radically affected by access to education, healthcare, food, living conditions, and the kind of test used. The average IQ in Kenya in 1948 was 72, and today the average is 97. A 25 point gain is not an indication of a change in intelligence, but rather a change in the ability of the people to better answer the questions on the chosen test.

It isn’t possible to compare the intelligence of humans on the basis of race or to compare humans with animals. Some animals do very well on some IQ tests. Koko, the gorilla that we have mentioned in previous issues of our journal, scores a 95 on some IQ tests according to articles in several popular magazines. Crows have high intelligence in solving certain types of problems. A food morsel floating on water in the bottom of a graduate frustrates children under eight years old because the can’t figure out how to get to it. A crow, however, will add pebbles to the graduate until the food floats up to a place where the crow can reach it. Who has the most intelligence?

Human uniqueness is not in our intelligence. It is our spiritual nature that sets us apart and allows us to do things such as art, music, worship, etc. Mentally challenged humans do these things, but intelligent animals do not. Animals may be intelligent and even score high on some IQ tests, but they do not have the capacity to feel guilt, to be sympathetic, or to create. IQ and intelligence aside, humans are unique because of our spiritual nature. We are created in the image of God, and that uniqueness is embodied in what the Bible calls “the soul.”

New Human Organ Discovery

There Is a New Human Organ Discovery
With all that science knows about the human body, it is truly amazing that they have just made a new human organ discovery. Scientists at the New York University Langone School of Medicine have announced the discovery of a previously unknown organ in the human body. They gave it the name “interstitium.”

The human body is about 60% water, most of which is in the cells. The interstitium is a network of fluid-filled spaces, and it holds about 20% of all the fluid in the human body. The reason this organ wasn’t detected earlier is that researchers treat and dehydrate the tissue samples before they put them under a microscope. That causes the interstitium to collapse. Until now researchers saw the interstitium as a dense wall of the protein collagen. They now realize that it is not a wall but an “open, fluid-filled highway” supported by a lattice of collagen.

The interstitium organ plays a major role in the immune system. Interstitial fluid is the source of lymph, which sends out white blood cells to fight infection. The interstitium’s role in the body’s battle against infection is significant, and this discovery may change how some difficult infections are treated.

Medical researchers discovered the interstitium by using a new imaging technique called probe-based confocal laser endomicroscopy (pCLE) to examine living tissue. They found interstitium tissue under the surface of the skin, in the lining of the digestive tract and lungs, and surrounding the muscles. This new human organ discovery helps explain how cancer cells spread throughout the body.

We still have much to learn about the design and function of our bodies, but we see God’s wisdom and the complexity of His creation as we grow in our understanding of how our bodies work. David said it best in Psalms 139:14, “I am fearfully and wonderfully made, marvelous are your works God, and my soul knows that very well.”

CRISPR and God’s Design

CRISPR and God's Design
The general media and scientific journals have given great attention to something called CRISPR (pronounced like the name of the refrigerator drawer where you stash fresh veggies). CRISPR was first reported in scientific journals and papers in 2012. Now it is being used by scientists all over the world as a method to modify human embryonic stem cells and answer questions about basic biology and development. Here is a sample of what Wikipedia says about it:

“CRISPR is an abbreviation of Clustered Regularly Interspaced Short Palindromic Repeats… A simple version of the CRISPR/Cas system, CRISPR/Cas9, has been modified to edit genomes… CRISPR/Cas genome-editing techniques have many potential applications, including medicine and crop seed enhancement. The use of CRISPR/Cas9-gRNA complex for genome editing was the AAAS’s choice for the breakthrough of the year in 2015. Bioethical concerns have been raised about the prospect of using CRISPR for germline editing.”

That last statement about this technique concerns many people. Are we “playing God” feeling that we can improve on what God has created? Is human genetic engineering going to threaten a catastrophic mistake in the future? Hollywood is already on this with dramas like Netflix’s Luke Cage.

CRISPR exploits something that microbes commonly do in the natural world. Bacteria defend themselves against viruses and other DNA in the environment by having snippets of foreign genetic material as molecular spacers which serve as borders. What scientists are doing is to pick those characteristics that CRISPR can use to eliminate a bad gene and insert a good one in place of it. We are taking something that God has designed into nature and using it to eliminate genetic disorders that may have been caused by human abuse of the environment.

This could be the tool to eliminate nerve damage and give quadriplegics and paraplegics full use of their arms and legs. Trials are already going on to eliminate cystic fibrosis, hemophilia, muscular dystrophy, many forms of cancer, sickle cell anemia, beta thalassemia, and leukemia. This is not replacing God’s original design but rather using some of the tools God created to repair things damaged by time and human abuse. Scientists are harnessing an ancient biological process to edit the code of life. God’s design is what makes this possible and offers great hope for the future of people afflicted with disorders which have not been within our medical reach in the past.

Brain Uploading

Brain Uploading
How would you like to have your brain uploaded before you die so that your consciousness could be preserved? That is the goal of a brain uploading company called Nectome.

The company wants to deliver a “100-percent-fatal” service to terminally ill patients. They are developing a process that fills the patient’s arteries with embalming fluids. The result is that the patient will die, but the brain will be preserved. Their process is supposed to preserve the links between the neurons in full detail. Then Nectome will view those links with an electron scanning microscope. Their goal is to preserve those links to revive the consciousness of the deceased person. The company hired lawyers to work out the legality of this process under California’s physician-assisted suicide law.

Nectome was founded by graduates of the prestigious Massachusetts Institute of Technology (MIT) and received funding from a famous Silicon Valley startup incubator. The brain preservation project involved a collaboration with MIT and received a grant of almost a million dollars from the National Institute of Mental Health (NIMH). They also received a prize of $80,000 from The Brain Preservation Foundation for preserving a pig’s brain using their process. MIT severed ties with Nectome just a few days ago after previously publishing a favorable article in the MIT Technology Review on March 13.

After the article in MIT Technology Review, several leading neuroscientists criticized the idea of brain uploading after preserving a brain from a live person. Nectome has removed a statement about being able to “back up” people’s minds from their website. They are now saying that they have no plans to do this in “the foreseeable future.” Robert McIntyre, the co-founder of Nectome, recently said, “…we don’t mean to imply that electron microscope image data is the only thing we would need to reconstruct consciousness or even memories.”

We have said for a long time that there is more to humans than just the physical body or the neurons in our brains. There is a spiritual aspect that cannot be preserved by any scientific means. By its very nature, it cannot even be adequately studied by any scientific means. We are created in the image of God with a soul that can live forever. Brain uploading, if it ever works, can never preserve the essence of who we are. Only God can do that. We must place our hope in Him, not in a company no matter how prestigious or well-funded it might be.

We Need Each Other

We Need Each Other
God has designed humans to have a unique relationship with God and each other. The terms “brother” and “sister” in the New Testament are a reflection of this relationship. We need each other as we face the challenges of life. When God created man, He said: “It is not good that man should be alone, I will make a helper suitable for him” (Genesis 2:18).

Researchers at the University of Colorado, Boulder conducted a study of 22 heterosexual couples who had been together for at least a year. They wanted to see how the simple act of a human touch affected various scenarios in life. To conduct this test, they divided the couples into different groups at different times. In one grouping they held hands. Another group sat nearby but didn’t touch. In a third group, the people were in different rooms.

The researchers used brain scans to study each of the groups. They conducted scans before applying a mild pain and again after applying the pain. The tests indicated that holding hands reduced the intensity of the pain by 34%. When the couples held hands, their brain waves became synchronized, especially when the women were in pain.

The conclusion of the researchers was: “We have developed a lot of ways to communicate in the modern world, and we have fewer physical interactions. This research illustrates the power and importance of human touch.”

This experiment gives scientific proof of what we probably already knew from experience, that we need each other.

New Life Behavior Ministries

New Life Behavior Ministries
New Life Behavior Ministries is a project of the Kings Crossing Church of Christ in Corpus Christi, Texas. For years we have worked with Buck Griffith and that ministry.

We refer prisoners completing our courses to them. Their team members visit the prisoners and provide personal needs and baptism if requested. We also refer prisoners with drug problems to their CASA study. CASA is an acronym for Christians Against Substance Abuse. This program has had a hugely beneficial effect on recidivism.

The New Life Behavior Ministries has begun a “Vet Net” program which offers special postage-paid courses (inside the United States) to veterans of all branches of the service and their family members–active or reserve. The top five courses in enrollment numbers are:
Christian Marriage Skills
Attitudes and Behaviors
Christians Against Substance Abuse
Managing My Anger
The “Seeker” Bible Study Series

We would like to make our readers aware of this great program, especially those working with military families. Contact information is:

Alcohol and Dementia

Alcohol and Dementia
“Heavy drinking takes an irreversible, long-term toll on the brain, increasing the risk of all forms of dementia.” That is the conclusion of an exhaustive study of alcohol and dementia. The study involved more than a million adults diagnosed with dementia from 2008 to 2013.

Nearly 60% of early-onset dementia cases were associated with alcohol-related brain damage. Alcohol is toxic to brain cells and reduces blood flow to the brain. People who are intoxicated have literally poisoned themselves. The radical increase in dementia in many forms in our culture is a consequence of the persistent use of alcohol.

When you add the use of nicotine, meth, pot, and other recreational chemical agents to the effect of alcohol and dementia, it is clear that we have an epidemic of brain damage afflictions ahead of us. God has told us that our bodies are special. First Corinthians 3:16 tells us that our bodies are “the temple of God.” First Corinthians 6:15-20 warns against the incorrect use of our bodies. These words are not just about religious separation. God has designed our bodies and our brains for the long haul, and taking care of what God has given us is a sacred responsibility we all have.

Not all dementia is a product of individual abuse. We are realizing more and more that our abuse of the environment also brings us great pain of all kinds. The chemicals we get in our food and the polluted air we breathe are also factors. Christians should be leaders in taking care of what God has created. “The Lord God took the man and put him into the garden to dress it and to keep it” (Genesis 2:15). We are the caretakers of the creation, and we have tended to exploit it rather than to take care of it. The consequences have been disastrous, and that must change.

Incredible Human Brain

Incredible Human Brain
As more and more scientific data becomes available, the incredible complexity of the cosmos and our world becomes clearer. A classic example of that is the incredible human brain.

The human brain is not exceptional on a chemical basis. Carbon, hydrogen, oxygen, and nitrogen are the fundamental materials that are present in all brains with traces of various metals also contributing a small part. What is remarkable is the design of the brain and what it can do.

Recent measurements show that the human brain can hold about one petabyte of data. That would be equivalent to a million one gigabyte flash drives. The brain uses more energy than any other organ in the body, but it is only 2% of our total body weight. There are 52 sections to the human brain, each one containing different cells allowing us to do the different things we can do. Every neuron contains about .07 volts of energy. Since a human brain has 86 billion neurons that adds up to about six billion volts–equivalent to 477,777,777 car batteries.

The brain is 75% water, weighs about three pounds with half a pound of that being fat. The incredible human brain is a designed structure that we still have much to learn about it. Our brains speak eloquently of God’s design and the wisdom of God’s creation.
