Description
Us and Them: The Science of IdentityDemocrat and Republican. Meat Eaters and Vegetarians. Black and White. As human beings we sort ourselves into groups. And once we identify ourselves as a member of a particular group say, Red Sox fans we tend to feel more comfortable with others of our own kind, rather than, say, Yankees fans. Yet we all belong to multiple groups at the same time one might be a woman, a mother, an American, a violinist. How do we decide which identities matter and why
Democrat and Republican. Meat Eaters and Vegetarians. Black and White. As human beings we sort ourselves into groups. And once we identify ourselves as a member of a particular group--say, Red Sox fans--we tend to feel more comfortable with others of our own kind, rather than, say, Yankees fans. Yet we all belong to multiple groups at the same time--one might be a woman, a mother, an American, a violinist. How do we decide which identities matter and why they matter so much? And what makes us willing to die for, or to kill for, a religion, a nation, or a race?In this award-winning book, David Berreby describes how twenty-first-century science is addressing these age-old questions. Ably linking neuroscience, social psychology, anthropology, and other fields, Us and Them investigates humanity's "tribal mind" and how this alters our thoughts, affects our health, and is manipulated for good and ill. From the medical effects of stress to the rhetoric of politics, our perceptions of group identity affect every part of our lives. Science, Berreby argues, shows how this part of human nature is both unexpectedly important and surprisingly misunderstood.
Humans need our tribal sense--it tells us who we are, how we should behave, and links us to others as well as the past and future. Some condemn this instinct, while others celebrate it. Berreby offers in Us and Them a third alternative: how we can accept and understand our inescapable tribal mind.
" A] brave book. . . . Berreby's quest is to understand what he sees as a fundamental human urge to classify and identify with 'human kinds.'"--Henry Gee, Scientific American

The blade is not sharpen.
Style: Lawn Edger w/(1) 4.0 Ah Battery
I had no problems assembling the equipment. The problem is with the blade. It doesn't have any sharpen. I bough spares blades which have a different configuration and better edge. However I haven't been able to unscrew the bolt in order to install the new blade. It is extremely tied. One would think that you purchase this equipment, at a high price, and would be able to use it right away. In your dream. This is a Third World Country selling things at an incredible high prices, for the profit of the American companies using the manpower of other Third World Countries or China.
Since the blade is not sharp, when you try to use the equipment it got disconnected. Therefore it does not work with the blade that comes from the manufacturer. Total disaster.

Worx very well!
Style: Lawn Edger w/(1) 4.0 Ah Battery
Worx very well. ;)
More power than I expected from a 20v cordless machine. And with the 4Ahr battery it comes with, I was able to do the drive, walks, and patio without having to change batteries. I own 2 Worx string trimmers, chainsaw, hedge trimmer, drill impact driver, and leaf blower. Love them all.

Problematic instructions
Style: Lawn Edger w/(1) 4.0 Ah Battery
The product is great once u figure out how to assemble. The instructions don’t do it. I was not happy. Every part was a challenge. The instruction book only shows a photo but not how to get it to look like the photo.
