一些简单粗暴的生活小技能：有哪些技能是我可以在1分钟内学会但却受用一生的？
Sahil Tripathi:Here is a clever method to estimate how far away something is from you;
1,Hold your arm straight with your thumb up.
2,Close one eye and align the tip of your thumb with the object lying away from you.
3,Now switch your eye(close the other eye now)
4,Your thumb will seem to change position
Now … estimate how far it moved (you could imagine the length of a car or something as shown in the figure below)
Multiply that by 10 and you have an estimate of how far away that object is. ;-)
这是一个可以帮助你测算某个物体距离你有多远的实用技能
1，伸直你的手臂同时翘起你的大拇指
2，闭上一只眼睛，把你的大拇指对准离你有一定距离的目标物体。
3，现在睁开你的眼睛，同时闭上你的另一只眼睛。
4，此时，你大拇指的位置好像移动了。估计下你的大拇指位置的移动距离。（如下图所示，你可以想象一下一辆车的长度，同理可运用于其他事物）
将该距离乘以10，你就可以得知此物大概离你有多远了。
Example
Here your thumb seems to jump about half a car length.Half a car length is about 2.5 meters.Times 10: the car is about 25 meters away.
例如：
在这张图中，你的大拇指位置大概移动了半个车子长度的距离，大约是2.5米的实际长度，把它乘以10，我们就可以估计出这辆车距离我们大概是25米远。
How it works
这个技能的原理是这样的：
The distance from your eyes to your thumb is about 10 times the distance between your eyes
你的眼睛到你大拇指的距离大约是你两眼之间距离的10倍
And so the distance to the far object is also about 10 times the width your thumb seems to move at the far object.
同样的，你跟物体的距离也是你大拇指在目标物上移动的距离的10倍。
This works because the triangles are similar, and so the relative lengths are the same.
这之所以成立是因为相似三角形定理，所以相对长度都是相等的。
This is a very simple trick. The next time you go to the petrol bunk, don’t be confused about which side of the car has the fuel lid.
这是一个非常简单的技能。下一次你开车去加油站加油时，不用再琢磨到底哪一边才有油箱盖了。
If you look at the little gas indicator on your dashboard (instrument cluster), you should see a tiny arrow next to it. That arrow actually points to the gas tank (fuel lid) side of your car. Now you’ll never forget where it is again!!!!!!!
看看仪表盘上的油气指标，你应该可以看到一个小箭头。实际上，这个箭头就是指向你车上的油箱盖方向。好了，下次你就肯定不会又忘记这个油箱盖到底在哪边啦！！！！！
I thought of posting this trick on quora when my friend and I had gone to the petrol bunk and he didn’t know about this.
有次我和我朋友一起去加油站加油，他居然不知道油箱盖在哪边，那时我就想着应该把这个小技能分享到quora上了。
There are times when we suffer from cough and cold and the most annoying thing during this time is blocked nose (Nasal Congestion).
我们经常都会感冒，而最烦人的时候就是遇上鼻塞。
Incase, if you don’t happen to have any nasal spray like otrivin around you, there is one way in which you could clear that blocked nostril passage.
万一你碰巧没有带任何通鼻剂在身上，有一个办法可以帮你保持鼻子畅通
Sleep on the opposite side of the blocked nostril 。
向着鼻子通畅的那边侧着睡。
For example: If your left nostril is blocked, try to sleep on right side of your body such that your left nostril is at a level higher than your right nostril. In 5-7 minutes the blockage starts to clear way for fresh air to breathe.
举个例子，如果你左鼻孔鼻塞了，尝试往右边侧身睡觉，这样你的左鼻孔就会高于你的右鼻孔。等个5到7分钟之后，你的左鼻孔就会慢慢通了。
Use a pause instead of ‘but’ while apologizing.
在道歉的时候，比起说“但是”两个字，不如停顿一下。
We all know whatever said before the ‘but’ was a moral obligation. It also makes your apology sound artificial.
我们都知道，不管你前面说什么，后面加个“但是”就显得你这样做好像是出于道德上的义务，这也让你的道歉听起来好虚伪。
Eg.
I’m sorry for the ordinary code but we had deadlines.
I’m sorry for the ordinary code. We had deadlines.
Smooth way of passing the blame as well :D
做个对比：
对于这个一般性要求我表示很抱歉，但是我们有时间限制的。
对个这个一般性要求我表示很抱歉。我们有时间限制。
这也是一个避免抱怨的温和方法有木有。
