Higher Intelligence Predicts Longer Lifespan?

intelligence

A recent study in the International Journal of Epidemiology puts forward the proposal that: The association between intelligence and lifespan is mostly genetic

We are looking forward to more research in this area even though we are quick to be suspect of findings when genetics are put forward as the main or sole feature that accounts for the differences found.  Nonetheless, this is an interesting study.  They summarized their finding in plain language:

Key Messages

  • It has been reported that brighter people live longer; we asked ‘why?’.

  • We found, using data from three studies, that the small association between being brighter and living longer was mostly genetic in origin.

  • This is a key finding in cognitive epidemiology; it is a further indication that intelligence is not just ‘school-smarts’.

As Long as We Believe That We Need Things to Make Us Happy…

nisargadatta_maharaj

As long as we believe that we need things to make us happy, we shall also believe that in their absence we must be miserable. Mind always shapes itself according to its beliefs. Hence the importance of convincing oneself that one need not be prodded into happiness; that, on the contrary, pleasure is a distraction and a nuisance, for it merely increases the false conviction that one needs to have and do things to be happy when in reality it is just the opposite.

But why talk of happiness at all? You do not think of happiness except when you are unhappy. A man who says: ‘Now I am happy’, is between two sorrows — past and future. This happiness is mere excitement caused by relief from pain. Real happiness is utterly unselfconscious. It is best expressed negatively as: ‘there is nothing wrong with me. I have nothing to worry about’. After all, the ultimate purpose of all sadhana [spiritual practices] is to reach a point, when this conviction, instead of being only verbal, is based on the actual and ever-present experience.

Paul Stamets on the Question of Should you eat raw Mushrooms

paul_stamets

Paul Stamets, a well known and esteemed mycologist, answers the question of whether or not mushrooms should be eaten raw for nutritional or health benefits.

The crux of the answer is contained in the following quote but his article goes into more detail:

No, absolutely not! Raw mushrooms are largely indigestible because of their tough cell walls, mainly composed of chitin. Eating raw mushrooms can provide flavor, but not nutritional or health benefits. In some cases, eating raw mushrooms could be dangerous.

Paleolithic Diet Decreases Cardiovascular Risk Factors in Type 2 Diabetes

paleolithic_diet

Or so says a study from 2009 in the Journal of Cardiovascular Diabetology.

Background: Our aim was to compare the effects of a Paleolithic (‘Old Stone Age’) diet and a diabetes diet as generally recommended on risk factors for cardiovascular disease in patients with type 2 diabetes not treated with insulin.

Conclusion: Over a 3-month study period, a Paleolithic diet improved glycemic control and several cardiovascular risk factors compared to a Diabetes diet in patients with type 2 diabetes.

Lyme Disease on the Rise

See this interesting article from qz.com:

Lyme disease is spreading faster than ever and humans are partly to blame

Nymphs, though, are roughly half the size of adults, about the size of a poppy seed. Tiny enough to pass for a smallish mole or freckle, they’re far harder to find than adults are; no surprise, then, that most human Lyme infections come from nymphs. All you can do is to take precautions against getting bitten, search for ticks thoroughly, remove them carefully if you find them, and look out for Lyme symptoms afterwards. Here’s advice on how to do all those things.

We have a thread on our discussion forum about Lyme disease.
