Further research needed: referring to the item below (time goes backwards in here) I should point out that Omega 3 is also linked by some research to being good for Depression, hyperactivity, allergies, heart disease, Crohn's disease, rheumatoid arthritis and cancer, etc.
Check it out.
The (allegedly ideal) Mediterranean diet for omnivores includes plenty of fish, and relatively little meat. There is certainly some kind of link with regular fish eating and getting enough of these important fatty acids.
Personally, I prefer being a guinea pig for the plant-based forms. I am fairly erratic in my consumption of them, but I try to keep it up when I can.
On the national tv test for 'intelligence' (whatever that is) I scored higher than the people in the studio, and one point higher than the best on-line participant. I am not bragging, just saying what happened. So I don't think I am seriously lacking in these particular nutrients (although good genes help with some of this stuff - and the ability to synthesise some of the things you need).
I didn't watch the programme in the mayhem of realtime, but video'd it. I still did the test fairly, though - no rewinding, or pausing. I don't care what it means, I just enjoyed the mental exercise. I don't want to join MENSA (even if I could pass their more rigorous tests. But I think I have a grasp on what intelligence might mean (and it's not all blessings, being the one-eyed man in the kingdom of the blind). And I agree with Julie when she points out the cultural bias in IQ tests - especially when I was a child and the 11+ test in the UK was loaded towards boys.
Still, this was a generic test, with a large sample base.
When I think about intelligence I know what I mean, but it's hard to define. I feel like St Augustine "I know what time is until you ask me to define it." [paraphrase, preceding research and correction].
Still, I empathise with the idea that the planet is smart (Gaia), and that the universe is smart (not The Great Designer - noun - but smarts in action - evolution and other emergent phenomena - verbs).
And I know I could still work on my 'emotional intelligence'. There's always more work to be done in the world of Lifelong Learning.
Stupid, however, we can easily do without.
