We experience a burst of pleasure when we share our thoughts,and this drives us to communlcate.It is a useful feature of our brain,because it ensures that knowledge,experience and ideas do not get buried with the person who first had them,and that as a society we benefit from the products of many minds.Of course,in order for that to happen,merely sharing is not enough.We need to cause a reaction.Each time we share our opinions and knowledge,it is with the intention of having an impact on others.Here's the problem,though:we approach this task from inside our own heads.When attempting to create impact,we reflect on what is persuasive to us,our state of mind.our desires and our goals.But if we want to affect the behaviours and beliefs of the person in front of us,we need to understand what goes on inside their head.

资料：What，if anything，do we gain by clinging to our antioxidant supplements？
Very little，according to an accumulating body of research. We don’t need massive doses of antioxidants，we need stress to compel our own bodies to create antioxidants.“Everybody thinks oxidation is bad，and that antioxidants are good，”says Dr.Jones，“That’s bogus. A little bit of poison is good.”
That poison can actually come from plants，especially those that have survived harsh conditions. Foods that have survived harsh conditions make us stronger by stressing our bodies，not because they’re rich in antioxidants.
As the science quarterly Nautilus explains，plants have developed an arsenal of chemicals to help them ward off insects and grazers. These“antifeedants，”when ingested by humans，trigger the body to release proteins and activate genes that “produce antioxidants，enzymes to metabolize toxins，proteins to flush out heavy metals，and factors that enhance tumor suppression.”
Plants prepare your body to handle toxins in the same way as exercise prepares you to race-by stressing your body. And supplements，says Dr.Hooper，interrupt this process.
“These antioxidant supplements are like a Trojan horse，”continues Dr.Hooper. They say，I’m a good guy. You guys go to sleep and while the defense is asleep the antioxidants get rid of any oxidation. It puts the defense-system’s army to sleep.
While Dr.Jones acknowledges the benefits of vitamin E for muscle cramps and macular degeneration，he doesn’t approve the idea that it improves one’s physical performance. He suggests that athletes in intense contact sports such as soccer and football benefit from trauma. “Players have to be hit with pads on Tuesdays and Thursdays in order to compete on Sundays-they need that actual trauma.”he says.
“Everything in our society is geared toward，How can we reduce stress？”adds Dr.Hooper. “When it should be just the opposite. We need stress. Stress is good.
