An article about the possiblity that a lot of frailty (serious loss of energy, mobility, and mental focus) could be low-intensity cardiovascular problems, and also evidence that exposure to good or bad ideas about aging affects people's capacities. Even minor or subliminal exposure to positive or negative views of aging causes measureable differences.

Speaking from experience with self-hatred, I notice real differences in my ability to do things when I can shut it off. This is especially relevent since a lot of what I tend to attack myself about is incompetence.

This is one of those "everything they've been telling you is wrong" articles. It looks as though genes might have rather little to do with lifespan. A big study of identical twins found an average ten-year difference in lifespan, and no one knows why. The difference isn't just people who died young of accidents screwing up the stats.

One hypothesis which isn't mentioned is that gene expression can get turned on or off, so that people with the same genes don't necessarily get the same effects from them.

This one is about how much health and longevity have improved in the past century and a half. It looks as though a lot of the change is better prevention of disease (disease can have long-term debilitating effects, even cancer, which was a surprise) rather than lifestyle. It backs up something I'd noticed--people don't age as fast as they used to--the article says that the diseases of aging now kick in about ten years later.

Here's a topic page with all three articles. It might be worth checking on now and then.

I wonder how much of aging is psychological? I do stuff at almost fifty that few people would have considered appropriate for an (almost) fifty year old a cxouple of generations ago. I confess that without modern anti-inflammatories, physiotherapy etc I might not be able to but I suspect attitude is important.

At least some of it is. Also, a lot of what looks like aging is accumulated inefficient movement habits, and I can believe that those get worse if you expect life to be bad.

Interesting.

The one on the twin study did mention different gene expression, which I think is the same as what gets turned on or off.

I like both how many hypotheses and assumptions they tested and refuted (e.g., that the first-born of a pair of twins will be healthier) and the comment that randomness is the "hand-waving explanation."

Oh. However, I will refer to this as failure to check carefully rather than a senior moment.

Failure to check carefully, and maybe that you were pattern-matching a phrasing they didn't use.

No, I'd read it a day or two ago, and thought I'd remembered it accurately.
