There are lessons in at least two directions for this. One of course is that I was correct to look out for his welfare. The opposing lesson was that I should not legislate him away from taking a small risk. My friend is not frail. He can fall in a reasonable place and not get injured. And continuing to do the things that are important to him is very important in his continued viability in many dimensions. I have been thinking about continued challenge and exercise as one ages, and it appears to be even more important than I had thought. This is but one small example.

The link here to BILL MOYERS JOURNAL on Single Payer Health Insurance will take you to one of the better discussions that I have heard about this topic. I am interested in your comments, and any other useful references on the topic.

It is unlikely that augmenters have a significantly shorter lifespan than do reducers. If you believe the life insurance companies, it may even be the reverse, because at least the last time I checked, they gave better rates for high school graduates who had strong academic records.
So this personality dimension also has to be taken into consideration when thinking about friend networks. The augmenters simply do not need or want as many friends. Reducers tend to have larger friend networks. So the material in my previous post has to be understood with a little more nuance than I first expressed it.
One way to think of it is in terms of augmenters who have relatively strong friend networks for augmenters, and reducers who have relatively strong friend networks for reducers. For each of these the observations might hold relative to those with weaker friend networks in each category. One might also argue that some augmenters do not need many friends, have very small friend networks, and so what! As long as they do not have an accident, they are just fine. But they are probably a pretty small part of the population. There are many more who would be better off for having a network of friends suitable for them.
A great research topic for somebody.

Now we have an article in the New York Times, http://www.nytimes.com/2009/04/21/health/21well.html?em=&pagewanted=print that presents some very compatible research results. A brief summary of research in the article identifies impacts of long term friendships on survival from breast cancer, reduced risk of heart attack and reduced fatalities from coronary heart disease, and reduced incidence of colds. One might ask whether this is alternatively a result of strong local relationships in addition to strong longterm relationship, that is, that people who have strong longterm relationships (at any geographical distance) also have strong local relationships, and it is really the local relationships that make the difference. The research is inconclusive, but the Times article seems to indicate that the longterm social relationships are actually more important than family relationships.
There is a line of unasked and unanswered questions that I pose about the question of whether such relationships extend to people's enduring capability to walk and run well. Frankly, I would bet that there is a relationship. Here is some introductory thinking about what the intermediate dynamics might be.
- People with good relationships would have a sense that life is worth living and in fact enjoyable, which would lead to continued physical vigor.
- People would enjoy and have fun walking in order to connect with their friends.
- People with friends would not give up, and thus would be better at recovering from injuries and problems.
- Such people would continue walking and maintaining themselves because they have something to live for. One of the problems of living into ones 90s is that many or all of one's friends pass away and one is left isolated. The solution to this is the development of new friendships, particularly with younger people. I have seen this occur when older people retain their mental aliveness and curiosity so that they are interesting to talk to. This again comes back to friendships.
- The ability to walk competently enables seniors to maintain relationships better and to continue to value them.
- Continued ambulation reduces the likelihood of depression and isolation, and these lead to continued ambulation. In some of what I have seen, loss of ambulatory competency results from not maintaining oneself. So friendships that reduce what leads to this will also reduce loss of ambulatory competency.
- In conclusion, lack of isolation, ambulatory competency, and linkage with friends are in many ways synonymous.
Possibly the most intriguing research finding in relation to this is summarized near the end of the Times article. Students wearing a heavy backpack were asked to estimate how steep a hill was in front of them. The students who stood beside a friend saw the steepness of the hill as being significantly less than those who stood alone in front of the hill. It would appear then that the task of walking up the hill, or for that matter, on a level surface if it is trying, is made more easy if one has the sense of the presence of friends. This would suggest strongly that friends make a difference for walking.
I am very interested in what others may have to say about this.

- body mass index
- smoking status
- socioeconomic level
- family history of diabetes
- diagnosis of cardiovascular disease
- use of steroid drugs.
They calculated the relative importance of each of these factors, and incorporated them into a web page algorithm, that quite accurately predicts the 10-year risk for Type 2 diabetes. Based on the British population, there is an interactive Web version of the algorithm at www.qdscore.org. Postal code and ethnicity applies only to Brits, but the results are good even without those two parameters.See:
