Mayo Clinic Alumni Association. Refer a Patient. Executive Health Program. Goldman joined the NewsHour earlier last week to discuss the Health Affairs study and explain why continued research into delayed aging could open a lot of doors for the future of human health.

NEWSHOUR: Professor Goldman, thanks for joining us. To start off, can you give us a general background on what delayed aging is and its importance? This rising life expectancy means that aging in and of itself is now becoming the most important risk factor.

The confluence of these trends means that we now have a situation where we really need to think about whether we want to make a greater investment in this area of delayed aging.

NEWSHOUR: You say investment. How did you come to the conclusion that this concept is one that would pay off in the long run? GOLDMAN: We have developed a model that tries to predict the future of the U. So we started to look at the underlying reasons.

We really need a comprehensive approach to fighting illness. When you do that, you quickly start talking about how to deal with aging. NEWSHOUR: What would this concept of delayed aging look like for an ordinary person?

So, when we talk about adding years of life, we can ask: are these healthy life years or disabled life years? For example, if we improve treatment for stroke, the outcome is often one in which people have limited function and end up in assisted living.

However, if we could prevent stroke, we can live that extra time in a healthy state. Delayed aging is about adding healthy life years rather than disabled life years, thereby achieving compression of morbidity or at least forestalling it.

GOLDMAN: That is actually a function of two things. So actually, the table has been tilted towards treating disease rather than keeping people healthy.

When it comes to research and development, the playing field is tilted away from prevention and towards treatment. But things are starting to change.

Larry Page, the CEO of Google, and Art Levinson, who is the former CEO of Genentech, one of the most successful biotechnology companies, have just decided to develop a company called Calico to explore this type of science. I think the market has decided that this is an area worthy of investment.

NEWSHOUR: Give us a scenario. I do think it raises some questions about social cohesion. A simple example would be: should Medicare cover them? Can you give us a broader sense of what those impacts would be? GOLDMAN: The economic impact is very dependent on social policy, as I mentioned before.

The consequence for the fiscal debt and deficit would be relatively minor. Social Security is going to end up having to pay out for a lot longer. We have an opportunity to figure out how we deal with an aging society over a longer period.

Previous studies, he explains, were asking questions like "When you age, which genes are getting turned on and which genes are getting turned off?

But nobody was asking how the transcription process itself changes as we age, a line of inquiry that could yield insights to ultimately help us reverse, or stop, decline. Transcription is fundamental to Beyer's research as it is the process in which a cell makes an RNA copy of a piece of DNA.

This copy is important because it carries the genetic information needed to make new proteins in a cell. Proteins determine the health and function of the cells, and cells then structure all living things.

Throughout our lives, our cells regenerate, "but each cell is different, and what makes them different are the different genes that are activated in it," explains Beyer. There are many different types of cells in the human body: nerve cells, muscle cells, blood cells, skin cells, and so on.

And because each cell fulfils a different function, a different set of genes are activated transcribed in each cell type. The "machine" - as Beyer calls it - responsible for making the transcription copy of the gene sequences is called Pol II RNA polymerase II.

Previous research had already proven that low-calorie diets and inhibiting insulin signalling - blocking the signal between insulin and cells - could delay ageing and extend lifespan in many animals.

The investigation - a joint collaboration of 26 people across six different labs - first worked with worms, mice and fruit flies genetically modified to inhibit insulin signalling as well as with mice on a low-calorie diet to determine the performance of cell transcription in old age.

In both cases, Pol II reacted and travelled more slowly, making fewer mistakes. So, what are you waiting for? Always remember that what you put into your body will impact on the appearance of your skin. Unhealthy food choices can create havoc, so do your best to limit their intake as much as you can.

Too much sugar in your diet is bad for you as it modifies essential proteins in our bodies. If these proteins build up, they can contribute to everything from wrinkles to energy loss. So, if you want your skin to be at its healthiest-looking and beautiful best, then be sure to include lots of colourful vegetables, olive oil and good fats into your diet.

Vitamin A is essential to life and to your skin. It helps to control how cells divide, grow and mature. So, if the cells are healthy, then chances are that you will have healthy DNA too. The regular use of topical vitamin A skincare products will also help your skin to function normally and therefore look healthy and radiantly beautiful.

Regular exercise is a key factor in looking and feeling healthy. Remember, your skin reflects your mental and physical state.

If you are healthy and happy, your skin will be too. Dancing may help to relieve the appearance of inflammatory skin conditions. Regular yoga practice can help reduce the appearance of premature ageing. Even meditation can help flush away toxins in your skin as you breathe in the good and breathe out the bad.

Apply self-tanner rather than get a tan. Every time you get a tan, you prematurely age your skin. This holds true if you get a tan from the sun, a tanning bed, or other indoor tanning equipment.

All emit harmful UV rays that accelerate how quickly your skin ages. If you smoke, stop. Smoking greatly speeds up how quickly skin ages.

It causes wrinkles and a dull, sallow complexion. Avoid repetitive facial expressions. When you make a facial expression, you contract the underlying muscles. If you repeatedly contract the same muscles for many years, these lines become permanent. Wearing sunglasses can help reduce lines caused by squinting.

Eat a healthy, well-balanced diet. Findings from a few studies suggest that eating plenty of fresh fruits and vegetables may help prevent damage that leads to premature skin aging. Findings from research studies also suggest that a diet containing lots of sugar or other refined carbohydrates can accelerate aging.

Drink less alcohol. Alcohol is rough on the skin. It dehydrates the skin, and in time, damages the skin.

This can make us look older. Exercise most days of the week. Findings from a few studies suggest that moderate exercise can improve circulation and boost the immune system.

This, in turn, may give the skin a more-youthful appearance. Cleanse your skin gently. Scrubbing your skin clean can irritate your skin. Irritating your skin accelerates skin aging.

Gentle washing helps to remove pollution, makeup, and other substances without irritating your skin. Wash your face twice a day and after sweating heavily.

Perspiration, especially when wearing a hat or helmet, irritates the skin, so you want to wash your skin as soon as possible after sweating.
