About Aging and a Prolonged Life

The topic “about aging and a prolonged life” is always popular with people. CNN recently discussed this topic with the Nobel prize winner and molecular biologist, Professor Venki Ramakrishnan. He shared the 2009 Nobel Prize in Chemistry with Thomas A. Steitz and Ada Yonath for research on the structure and function of ribosomes. Ribosomes are sub particles in the cell responsible for making proteins. In the following I will summarize this interview.

What is aging?

150 years ago, people lived only about to 40 years. Today we can live up to 84 years in most countries. It is because medicine has learnt a lot about the reasons why diseases occur and how they can be cured. Physicians have a number of antibiotics available for those who suffer infections. Heart bypass surgeries and stents can prolong a person’s life when there is hardening of the coronary arteries.

Aging processes

The following aging processes occur all our lives:

  • DNA breaks happen in our cells, but repair mechanisms are in place that deal with this. With older age repair mechanisms are more sluggish.
  • Faulty proteins form inside cells, however, we have mechanisms to take care of that.
  • Chemical damage to molecules in our cells accumulates. The cells can only partially eliminate these.
  • Hormone disbalances occur during menopause and andropause. But anti-aging physicians can correct this by doing hormone tests and ordering bioidentical hormone supplements.
  • There are limits of what anti-aging medicine can do: osteoarthritis affects our joints; our muscles are aging and with it our heart muscle. Degenerative neurological diseases like multiple sclerosis, Parkinson’s disease and dementia occur frequently as we get older with no effective therapies.
  • The immune system weakens with age. To a certain extend vitamin D3 and other supplements can strengthen it, but only to a certain extent.

Systems working together in our body

Dr. Ramakrishnan said that our bodies work like cities. In it are various systems that need to work together to keep us alive. If a major system fails, we die. Some of the essential organ systems are the heart, the brain, kidneys, our gut, the lungs, the bone marrow and all our hormone glands. If one of these organs breaks down, we are in trouble. If an organ donor is not available, we perish. But even when everything is working together well, we are limited reaching a maximal lifespan of about 120 years. This has to do with limits of our cell metabolism and the aging processes mentioned above. Science has not found a way to prolong our maximal lifespan and likely will not find one soon. But there are various lifestyles that can prolong life as I mentioned here before.

Genetic effect on our lifespan

CNN asked Dr. Ramakrishnan what genetic effects there are that would transmit longevity from a parent who lived until 95 or older to a child’s lifespan. He answered the following:There is a correlation between the ages of parents and their children, but it’s not perfect. A study of 2,700 Danish twins showed that heritability — how much of our longevity is due to our genes — only accounted for about 25% of lifespan. Still, researchers have found that mutation in just a single gene can double the lifespan of a certain type of worm. Clearly there’s a genetic component, but the effects and implications are complex.”

Relationship between cancer and aging

The same genes are involved for the growth of the body at a young age, and the older person who comes down with cancer. In old age the same genes can cause cancer and dementia. Dr. Ramakrishnan said: “Our risk of cancer increases with age because we accumulate defects in our DNA and genome, which sometimes cause gene malfunctions that lead to cancer. But many of our cellular repair systems that seem to be designed to avoid cancer early in life also cause aging later.”

Apoptosis (programmed cell death) and senescent cells

The body has two mechanisms in place that counter the danger of developing cancer cells. Dr. Ramakrishnan explained: “For example, cells can sense breaks in our DNA that might allow chromosomes to join in an abnormal way, which could lead to cancer. To prevent that joining, a cell will either kill itself or enter a state called senescence, where it can no longer divide. From the perspective of an organism like us, which has trillions of cells, this makes sense. Even if millions of cells are destroyed this way, these actions protect the whole organism. But the buildup of senescent cells is one of the ways we age.”

Lifestyle changes that help you live longer

Dr. Ramakrishnan said that our grandmothers knew what a healthy lifestyle was. The following is a list of what science now confirms adds years to your life:

  • Don’t be gluttonous. Eating a variety of healthy foods in moderation can prevent the health risks of obesity.
  • Get exercise: this helps us regenerate new mitochondria, which are the powerhouses of our cells providing energy.
  • Avoid stress, which creates hormonal effects that change our metabolism and can accelerate aging.
More life prolonging points:
  • Get enough sleep. This allows our bodies to do molecular-level repair.
  • One of the newer findings is Dr. Longo’s fasting mimicking diet. Do a semi-fast once a month for 5 days with 500 to 600 calories per day. This helps you to shed 0.5 to 0.7 units of body mass index. It also stimulates your immune cells, your stem cells and elongates your telomeres. Long telomeres make you live longer.
  • Replacing missing hormones with the help of an anti-aging physician will add about 10 years to your life. I mentioned this earlier.

A few more points about longevity research

Dr. Ramakrishnan said: “Already the top 10% of income earners in both the US and the UK live more than a decade longer than the bottom 10%. If you look at health span — the number of years of healthy life — that disparity is even greater. Poorer people are living shorter, less healthy lives.” He said further about the concept of “immortality”: “I think this quest for immortality is a mirage. One hundred and fifty years ago, you could expect to live until about 40. Today, life expectancy is about 80, which, as author Steven Johnson has said, is almost like adding a whole extra life. But we’re still obsessed about dying. I think if we lived to be 150, we’d be fretting about why we’re not living to 200 or 300. It’s never-ending.”

Conclusion

CNN discussed the quest for longevity with Nobel prize winning Dr. Ramakrishnan. He pointed out that the aging process is due to a number of factors that work together. There are DNA breaks, faulty proteins, chemical damage to molecules, hormone disbalances and degenerative changes. We need to watch that we do not overeat, get regular exercise and eat a variety of healthy foods. In addition, we need to avoid stress, get enough sleep and replace missing hormones with bioidentical hormones. A newer boost to your health is the fasting-mimicking diet (FMD) from Dr. Valter Longo that helps you keep your weight in the lower body mass index range. Dr. Longo showed in animal experiments and with humans that the FMD elongates telomeres, which directly prolongs life.

Apply what helps your longevity

While it is far-fetched to believe that we now have a ticket to live for 120 years or longer, it is more important to know that we can do our part to spend our golden years in health and wellness.

Four Diseases Cause Most Of The Deaths

Four diseases cause most of the deaths around the world: cancer, cardiovascular disease, chronic respiratory diseases and diabetes. This story is the news right now. 50% of the 193 UN member states that signed a treaty in 2015 are falling short of their promise. They wanted to reduce premature deaths from these diseases by 2030. But this is not happening as this story shows.

I like to review these 4 key diseases and what we can do ourselves about eliminating them. We cannot afford to wait for things to happen on a national level. Rather we need to go to the grass roots of every country and change the risk factors that cause these 4 diseases.

Cancer

First, cancer is a disease of older people, unless strong genetic factors are present. In this case even children can get leukemia, brain tumors and osteogenic sarcoma. In older people DNA mutations and DNA breaks happen more often as we age. On the other hand, if we diagnose cancer in stage 1 or 2 (in the early stages), it is quite often curable.

Oncoblot test, a cancer screening test

Probably one of the less known new criteria is the fact that there is a very sensitive cancer blood test, called the Oncoblot test (released about 4 years ago by the FDA). The latest screening test that came out of the human genome project is called the Oncoblot test. It screens for 25 of the most common cancers. And it is screening for ENOX2 proteins from cancer cells. It is a 1000 USD test in the US that health plans will not cover, but it will screen for more than 25 different common cancers 6 to 8 years before they would otherwise become clinically manifest.

If you discover cancer with this early blood test and you treat it right away, you have a good chance to live a few years longer. You may come down with another cancer down the road, but treat it early again, and you will still have a better life expectancy. Remember: four diseases cause most of the deaths, cancer is one of them!

Cardiovascular disease

Furthermore, people develop cardiovascular disease from poor eating habits and a lack of regular exercise. There are a few percentage points of people with familiar high cholesterol. These people need to see their family doctor for a prescription to lower cholesterol. But the majority of people will do well by changing their diet into a Mediterranean diet; lose weight until their body mass index reaches a value of 21 to 24. With this diet it is important to cut out all refined sugar and starchy foods. Regular exercise in a gym will also prevent hardening of the arteries. Chelation therapy has been shown in this study to help reduce hardening of arteries.

Diabetes patients have accelerated hardening of the arteries

We know from diabetic patients who have accelerated hardening of the arteries how devastating cardiovascular disease can be. Heart attacks, strokes, kidney failure, amputations of the lower leg and blindness are just some examples. Even patients who do not have diabetes can get these complications at an older age. The key is to think preventatively, change the diet, exercise regularly and you will lower all those risks. Remember: four diseases cause most of the deaths; cardiovascular diseases belong to that group and are a major player.

Chronic respiratory diseases

There are different reasons why a person may develop chronic respiratory disease. A common disease is chronic obstructive pulmonary disease (COPD). COPD often has a link to smoking heavily as a younger person. This is where the damage to the lung tissue has started. Exposure to cigarette smoke leads to loss of elastic tissue in the bronchial tubes. The lungs have a difficult time to exhale to get rid of the CO2. The end result is that your breaths are shallow and you can’t get enough oxygen, because the lung is already filled with air.

Asthma and COPD

Another disease is asthma. Nowadays physicians can treat this condition well with a corticosteroid inhaler and salbutamol. Salbutamol dilates the airways by relaxing the muscles of the bronchial tubes. The corticosteroid keeps the lining of the bronchial tubes thin, so that the air can move in and out of the lung.

If asthma is not treated properly there can be permanent damage to the airways and the clinical picture would look similar to COPD.

With end-stage COPD patients the only therapy the physician can offer is continuous oxygen flow treatment. With power failures these machines that supply oxygen will stop working. People need to make provisions to have a back-up generator. Again, we need to remember: four diseases cause most of the deaths. Chronic respiratory diseases belong to them.

Diabetes

Patients with type-2 diabetes (Type 2 DM) are usually older than 30 years of age.

That’s why they are called “mature onset diabetes” or “adult onset diabetes”. For several decades a patient may “incubate” diabetes and have one or more of the diabetes risk factors, such as high blood pressure, obesity, high cholesterol or high triglycerides, but have normal blood sugars.

Physicians have followed patients like this for several decades in the well known Framingham Heart Study and found that a high percentage of them do come down with type-2 diabetes later in life. In the past this time of incubation was termed “pre-diabetes”. Now we call it “syndrome of insulin resistance” or “metabolic syndrome”. Diabetes belongs to the group of diseases that are associated with chronic inflammation in the body.

Causes of type-2 diabetes

Type-2 diabetes often associates with other endocrinological diseases such as Cushing’s syndrome (an adrenal gland hyperactivity) or acromegaly (increased growth hormone production). In these diseases other hormones are tilting the hormone balance by counteracting insulin thus leading to a relative shortfall of insulin, which is another cause for type-2 diabetes. There is confusion among scientists regarding possible genetic reasons for type-2 diabetes. The environment or weight gain may trigger various genetic loci that exist. The syndrome of insulin resistance has shown some connections between hypertension, obesity and type-2 diabetes.

Death in diabetics usually comes from a heart attack, a massive stroke, but it may also come from systemic infections, called sepsis. Dr. Taylor from Newcastle University showed on 30 volunteers that 43% of diabetics could be cured by a diet of 600-700 calories for 8 weeks. The medical literature also knows that regular exercise is beneficial for diabetics. It cannot be overstressed that four diseases cause most of the deaths; diabetes belongs to them and is a major player.

Four Diseases Cause Most Of The Deaths

Four Diseases Cause Most Of The Deaths

Conclusion

Four diseases cause most of the deaths. They were the cause of death for several years. They are cancer, cardiovascular disease, chronic respiratory diseases and diabetes. The secret is to minimize the impact of each of these diseases. You can prevent chronic respiratory diseases by stopping to smoke and treating asthma properly. To treat cancer successfully one needs to diagnose it early and remove it surgically. With cardiovascular disease chelation therapy has shown a difference. Otherwise a regular exercise program and a Mediterranean diet, which has anti-inflammatory qualities, will help. Dr. Taylor from Newcastle University demonstrated that he can treat diabetes with a low calorie diet. Each one of us has a responsibility to do something about our diagnosed condition. We cannot wait for magic cures. We need to do what has known benefits. Hopefully with these short hints will help you to improve your health.
