Oh! finally someone talking strongly against meat! I don't feel alone anymore... I think in something like a century we will all consider the meat-eating ancestors with perplexity at the least. It is only a matter of time.
(Lapis, I saw in your blog you link to "Meet you Meat", I had already seen it, wow! is it strong...)
There is also the issue of the heavy metals contained in ocean fish. In the old times this didn't exist. Anyway, I asked Erik a bit, he told me that in the far north poor people were in fact eating mainly fish, the richer traded some fish with cerals. He doesn't know of any case of longevity though. I think I read somewhere that the average age of sami people (the ones in the igloos) was 40 years (before they discovered alcohol and cigarettes), but that could also be because of the cold. In Denmark the average age is still 65!(but about Denmark I'm cheating, they are the junkiest nation on earth, you should see their super-markets OMG!)
