如果上課或者開會時昏昏欲睡，把你的一隻腳稍稍的抬離地面，看能堅持多久，你就不困了。

Use shaving cream as anti-fog. I used it on the inside of my motorcycle visor. Smear it on, let it dry, then rinse off and dry. It also works for bathroom mirrors. You can use it on a small spot so you can still see when you get out of the shower.
剃鬚膏可以用來當防霧劑。把它抹上在摩托車遮陽板的內側，晾乾，沖洗乾淨，再晾乾。浴室鏡子起霧也可以用這個方法，把剃鬚膏塗在鏡子的一塊地方，洗完澡鏡子還能看清楚。

對着吸塵器大喊，這樣你們家的狗就不會朝着吸塵器狂吠了。

That rubbing alcohol removes chewing gum. I』d go through a 20-layer-deep marketing funnel to get to that tip because it really does work.
醫用酒精可以去除口香糖。即便要經過20層劫難才能得到這個經驗，我也會去做。因為它真的有效。

You can do the Heimlich maneuver on yourself. Use a chair or countertop, press yourself against it (right under your rib cage), and press down hard. Should force air up and dislodge a blockage.
你可以給自己做哈姆立克急救法。用一把椅子或者工作檯，把自己壓在上面(放在你的肋骨下面) ，然後用力一壓。這會迫使空氣上升排出堵塞物。

The cheapest, most effective, and safest insecticide against roaches (especially those huge 「water bug」 roaches that we have in the South) is a spray bottle of mostly water with just a little liquid dish soap in it. Shake the bottle and get the water a little foamy, then spray the roaches. They will run, scramble, and attempt to escape, of course, but they will die. The soap film suffocates them faster than any chemicals will. Plus, it’s very easy to clean up and is safe around food (not that you want to spray soapy water ON your food).
對付蟑螂（尤其是南方那些巨大的 "水蟲 "蟑螂）的最便宜、有效且安全的殺蟲劑是一個找噴霧瓶，裡面放滿水，滴幾滴洗潔精。搖晃瓶子產生泡沫，然後噴在蟑螂身上。蟑螂會逃竄、掙扎，試圖逃跑，但它們必死無疑。對蟑螂來說，肥皂膜比任何化學藥劑都更致命。而且，這也非常容易清理，即使噴灑在食物周圍也很安全（不是要你把肥皂水噴在食物上）。

如果你的戒指被卡住了，滴幾滴windex(國外清潔劑品牌）就能順利取出來。我在珠寶店5年多的工作經歷教我的。

From the amazing book, The Gift of Fear, by Gavin DeBecker: 「A woman alone who needs assistance is actually far better off choosing someone and asking for help, as opposed to waiting for an unsolicited approach. The person you choose is nowhere near as likely to bring you trouble as the person who chooses you is.」
加文 · 德貝克爾在其著作《恐懼給你的禮物》中寫道: 「事實上，當女性孤身在外需要幫助時，最好主動向別人求助，而非等待他人來幫助你。因為選擇你的人遠比被你選擇的人更容易讓你遭到侵害。

Counting really slowly with the goal of reaching 150 is a decent way to fall asleep. If you have any thoughts during it, just let them play out, and if you forget what number you’re on just go from what you last remember. If you make any major movements, just start again. The goal is to force your brain to slow down and not have any jerky motions or thoughts, and eventually, reach such a level of carelessness that you eventually fall asleep without realizing it. Helped me quite a few times, especially with rain sounds. Hope it helps some of you too!
睡不着時，慢慢數數字，目標是數到150。如果有其他念頭，讓它去。如果忘記了數字，就從最後記得的開始數。期間有任何大動作，就重新開始數。這樣做的目的是迫使大腦慢下來，不要有任何突然的動作或想法，最終，達到什麼都不想的地步，你會不自覺地睡着了。這個方法幫助我入眠很多次，搭配雨聲尤佳。希望它也能幫到你們中的一些人！

如果生火的東西全都被打濕了，而你手上只有火柴和零食。玉米片可以當引子被點燃，燃出一團大火。

Put your onion in the freezer for 10 minutes before chopping it. It freezes the juices just enough to slow down the process of it turning into a gas, giving you a few minutes to chop the onion without tears. I learned this tip from a kid’s science show years ago and haven’t had to deal with onion tears since. So many people don’t believe me, and they are genuinely surprised when it works.
切洋蔥之前，把洋蔥放到冰箱裡10分鐘。低溫能減緩洋蔥變成氣體的時間，讓你切洋蔥不流淚。我是幾年前從一個兒童科學節目中學到這個方法的，從那以後我再也不會在切洋蔥時流淚了。一開始很多人不相信，但是當這個方法奏效時，他們驚呆了。

Vinegar in a plastic bag with a rubber band tied around any faucet will make the faucet like-new. I’m talking decade-old rust and stuff gone...and water flows like the first day. It also works on showerheads. You can unscrew those and leave them in a bowl full of vinegar.
把醋裝在塑料袋裡，用橡皮筋綁在水龍頭上，水龍頭會煥然一新。即使是十年的鏽跡也能消失不見，水龍頭的水流動像第一天那樣順暢。對於清洗蓮蓬頭也有用。把蓮蓬頭擰下來，放在一個裝滿醋的碗裡。

If your car is overheating, turn your heat on full blast. When you turn the heat on in a car, it pulls heat from the engine into the cab, thus cooling the engine. I was taught this in driver’s ed 23 years ago. When my buddy’s car would run really hot back in high school, I told him to turn the heat on. He wouldn’t. I had to convince him it was true by saying I would pay for the resulting damage if the temp didn’t go down. It was the wintertime, and that heat was so hot we had to roll the windows down. But we watched his engine temp drop. I don’t believe it’s especially uncommon, but if no one ever told you, it would seem counterintuitive. This doesn’t work on electric cars and, depending on your mechanical Issue, it may not work at all. It’s not a permanent fix, this is to get you somewhere to safely address this issue.
如果汽車過熱，把汽車暖氣開到最大。打開汽車的加熱器，汽車會把熱量從發動機吸入駕駛室，從而冷卻發動機，這是我23年前在駕駛課上學到的。高中時，我朋友把車開得過熱，我告訴他把暖氣打開，他不聽。於是我和他打賭，如果溫度沒有降下來，我賠償你的全部損失。那是個冬天，當時車內溫度太高了，我們不得不把車窗搖下來，我們看着車子溫度一點點下降。我不覺得這個方法很少人知道，但要是沒人告訴你，你會覺得它違反常識。這個方法不適用於電動汽車。根據汽車機械構造的不同，它有時也可能不起作用。不過這不是個一勞永逸的方案，這是為了讓你去某個地方安全地解決這個問題。

Clean jewelry with dish soap since other cleaning supplies might scratch it (like hand soap or anything that exfoliates) or chemically react with the metals (usually like harsh cleaning supplies) and dish soap is intended to clean glass and ceramic without scratching it and silverware without reacting with the metal, etc.
用洗潔精清潔首飾，其他清潔用品可能會劃傷首飾(比如肥皂或任何可以去除角質的東西) ，與金屬發生化學反應(通常是刺激性的清潔用品) 。但洗潔精是用來清潔玻璃和陶瓷的，它不會劃傷首飾和銀器，也不會與金屬發生反應。

Run your wrists under cold water or rub an ice cube on your pulse points to cool down all over quickly when you get overheated. It seems obvious but I didn’t realize it until last summer working in a warehouse with no AC.
當你特別熱時，將你的手腕放在冷水中，或用冰塊擦拭你的脈搏，可以迅速降溫。這個方法效果立竿見影，但直到去年夏天，我在一個沒有空調的倉庫工作時才發現這一點。

If you』ve written on a dry erase board (or any glossy surface) with a permanent marker (like a Sharpie), just draw over it with a dry erase marker and it will wipe right off.
如果你用記號筆在白板(或任何光滑的表面)上寫字，筆跡擦不掉時，只要再用白板筆在上面畫一下，字就會馬上擦掉。

Smell is closely associated with memory. If you’re studying for an exam, buy an odd scented eraser (like pickle scent). Every time you try to memorize something, take a sniff. Take that eraser to the test and sniff it when you’re having trouble remembering an answer.
嗅覺與記憶密切相關。如果你在準備考試，買一塊氣味古怪的橡皮擦（比如泡菜味）。每次背東西的時候，聞一聞。帶着橡皮擦去考試，當你記不起答案的時候聞一下就能想起來。
