One of the things he mentions is to not stress. How do you do this? I'm not a worry wart or anything, but sometimes it seems like I can't help my body's natural response to certain situations.

I think he means to just try to avoid stress. The way I do this is--

A) Avoid situations which I know will be stressful. Not all situations that are stressful are harmful in the long run, though. For me, meeting people is stressful, but it pays itself off as if you're lucky enough to come off as likable you may have new friends, which will reduce your stress. People who socialize have been shown to live longer and be happier, according to Richard Restak in his book "Think Smart."

B) If you're troubled by something stressful (which has already occurred), I find it best to locate the exact thing that is stressing you and why it's stressing you. If it's an exam coming up, I try talking it over with people and venting. This has helped me a lot. I'll recant Think Smart again, where Dr. Restak recommends asking yourself these questions:

"Am I going to allow this experience to determine the course of the rest of my life? Or am I going to take control of my life? What can I learn from this experience?"

He goes on to say:

"Mentally reformulating things in this way will increase your feeling of control and protect your brain from stress-induced damage. This is important, since loss of a sense of control is the main contributor to the stress response. No matter how stressful the situation, if you retain control of your attitudes and responses this along will lessen your stress--even if you can't affect the situation responsible for the stress."

Couple quotes:

"Not being able to govern events, I govern myself." -Michel de Montaigne (useful for stressful situations)

"If you are distressed by anything external, the pain is not due to the thing itself, but to your estimate of it. This you have the power to revoke." -Marcus Aurelius (had to remind myself of this today)

Hope this helps.

Thank you for linking to this interesting discussion on Reddit. Their discussion lacks a few key points. First, inflammation is an important cause of cellular (and DNA) damage. The standard weapon used by your innate immune system is super-oxide, a free radical! Avoiding chronic infections is likely to be an important key to longevity, especially for those prone to inflammation. Second, while "aging" is a natural mec…

Wouldn't dwarfs have less cancer simply because they have fewer cells that can become cancerous?

Earlier quoted context omitted.

My understanding is that we all have cancer cells in our body — the problem becomes when they get triggered. There may be something in the immune system that has something to do with this. What depresses me with this subject is that it seems like the more we know about it the more we understand how much more we really need to learn. Also as I get older I keep coming across more members of my peer group (and people I…

We all have tumors in our bodies, not cancer. Cancer is when the tumor metastasizes, and begins to grow out of control. Perhaps instead of hoping for a silver bullet to cure cancer, determine when/if your body is full of tumors, and do everything you can to prevent them from accumulating any more DNA damage.

I think one of us may be confused about the definition of metastasis. From (http://www.merriam-webster.com/dictionary/metastasis) it appears that metastasis typically happens after a cancerous tumor has been around for a while, when some cancerous cells escape the tumor and start dividing elsewhere.

That is nice explanation. As our ancestors used to say - Clarity is an evidence. ^_^

There is another simple point - who on earth will ever publish a study which proves that the whole ready food and fast food industry makes us sick, that the whole idea of office work (and driving a car!) is deeply wrong and that just vegetarian diet and regular exercise, e.g. agriculture work, and community of our equals is what we need because it defines what we are? ^_^

Of course, the study that shows that common sense has some sense will never be widely pushed through media. First, who will give you money to prove things that everyone knew but forgot? And corporations, who need to push more crap to get more profit, will stop it on very early stage, because that is the best strategy for them.

So, yes, diet, exercise and proper state of the mind (avoidance of stress, attachments, passions) together makes us healthy and younger, but people knew this for aeons without any Wikipedia articles. ^_^

So the natural question is - what can one practically do to try to postpone DNA damage as much as possible?

Slip-slop-slap (http://en.wikipedia.org/wiki/Slip-Slop-Slap), or just stay out of the sun as much a possible (do not stay in a bunker 24/7, as that would lead to vitamin D deficiency)

Those dwarfs seem to get even less cancer than you would expect given the reduced number of cells.

Also, on a related note, there's Peto's Paradox about why cancer rates are similar across species despite vastly different sizes (mice, humans, whales).

For a nice read about stress and the body's stress mechanisms you should have a look at Why Zebra's Don't Get Ulcers by Robert Sapolsky.

The book is more about the effects of stress than how to avoid it, but the author suggests:

1 - Exercise (pick something you enjoy, preferably aerobic) 2 - Meditation (seems to help while you're doing it, less clear on persistence of effects) 3 - Control - it's nice if you have (and feel) some control in your life. 4 - Have a system of social support. 5 - Religion and spirituality. Very loose ground here. 6 - Cognitive flexibility (different coping strategies for different stressors)

Personally, I've found that regular exercise is a big stress reducer. Particularly heart rate interval training, alternating periods of over 90% max heart rate with recovery periods below 70% max heart rate.
