使用被占用的时间（Use dead time）：这里的时间表示的是被浪费的时间或者是被使用的时间：比如说开车的时候，等待的时间，甚至是在花园中劳作的时间，这个时候可以听听电子书之类的。 （译者注：“一心二用”，或者是“挤海绵里的水”，利用零碎的时间，在地铁上，等待中学习，当然要注意行车安全，呵呵）
学习语言：比如说外语，方言等等。可以阻止脑的衰老，同时也可以接收新概念，训练大脑。
Rosemary：迷迭香。开窍醒脑，有待进一步证实。
专注力练习（Mindfulness exercises）：如果心乱如麻，还不如理理思绪，将要做的事情罗列下来（记在笔记本上），一件件的去做，暂时不要做的就不要总是在想它。【 原文：Concentration and clear thinking are more or less automatic once you remove distractions. Learn to stop and watch your busy mind. As you notice things that are subtly bothering you, deal with them. This might mean making a phone call you need to make, or putting things on a list so you can forget them for now. With practice, this becomes easier, and your thinking becomes more powerful.】
少吃会引发过敏的食物( Avoid foods that cause subtle allergies)：比如说小麦，玉米，花生，乳制品等，你需要体会一下，是不是这些食品并不适合你的体质，引起消化问题和“脑雾”。【原文：These can include wheat, corn, peanuts and dairy products. Watch yourself to see if you have a problem with any of these. They cause digestive problems and brain fog in some people.】（译者：真有点玄，那还吃什么呢，要多多注意就是了，西方人花生过敏的很多啊，呵呵。）
避免吃糖：任何碳水化合物都能够造成“脑雾 brain fog”，有时也称之为“糖忧郁 sugar blues ”，症状就是思维不清晰。原因是糖的摄入，会有更多的胰岛素参与到血液中来分解糖分。所以重要的脑力工作之前避免吃糖，面食，薯条之类的。【原文： Avoid sugar. Any simple carbohydrates can give you "brain fog." Sometimes called the "sugar blues" as well, this sluggish feeling makes it hard to think clearly. It results from the insulin rushing into the bloodstream to counteract the sugar rush. Avoid pasta, sugars, white bread and potato chips before any important mental tasks.】
Brain wave entrainment. The newest brain wave entrainment products are powerful tools for altering your brain function. Some will almost immediately relax you, while others will put your brain waves in a pattern that is most conducive to analytical thinking.

肌肉素：Creatine。【原文： This is a compound found in meat, used by athletes to help build muscle. Now the evidence is here to show that it helps your brain as well. Proceedings B , a journal published by the Royal Society reports that the research showed improvement in working memory and general intelligence resulting from creatine supplementation. The dose used in the study was 5 grams per day. This is about the level used to boost sports performance, and is as much as you‘d normally get in four pounds of meat, according to lead researcher Dr. Caroline Rae.】
避免过度肥胖：Avoid too much fat。实验室研究，脂肪过多，学习速度就会降低。所以吃橄榄油，或者其他不饱和脂肪酸的油吧。
少吃：吃的太多，消化系统需要的血液量就会更多，脑的供血量就会降低。
少吃可疑食物：Avoid suspect foods：人造色素、人造甜味剂、腌制品、白糖、高糖饮料、白面包、面粉制品等。【原文：There is evidence that the following foods can be bad for your brain: Artificial food colorings, artificial sweeteners, colas, corn syrup, frostings, high-sugar drinks, hydrogenated fats, sugars, white bread, and any white-flour products.】
吃早餐
避免糖尿病：
吃抗氧化食物：Eat foods high in antioxidants。可以保护细胞，特别是脑细胞：葡萄干、蓝莓、黑莓、大蒜、甘蓝、浆果、草莓、菠菜等等。
喝（红）酒：红酒中的抗氧化物质比较丰富。
适度饮酒：Use alcohol in moderation.。适度饮酒比不饮酒或者过度饮酒的人都要聪明。【原文：In a study at the University of Indiana School of Medicine, elderly light drinkers (fewer than 4 drinks per week) scored higher on tests of thinking abilities than non-drinkers. Those who drank 10 or more drinks per week scored lower. It is known that alcohol can kill brain cells, so moderation seems to be the key.】
学会使用工具和方法来辅助自己。【原文：Use systems. From the time I was ten years old, 12 x 49 was always (12 x 50) - 12. It‘s easier to figure in your head this way (588, by the way). I didn‘t get any credit for my personal algorithms then, but they are selling these shortcuts on late-night TV now, because they work. You can find your own easier ways to do mental math or other mental tasks, or read a good book on them.】
