Is it time to put a 'Full Stop' to everything?? What the hell is wrong with me??

教室里那台风琴叮咚叮咚叮咛
像你告白的声音动作一直很轻
微笑看你送完信转身离开的背影
喜欢你字迹清秀的关心

那温热的牛奶瓶在我手中握紧
有你在的地方我总感觉很窝心
日子像旋转木马在脑海里转不停
出现那些你对我好的场景

你说过牵了手就算约定
但亲爱的那并不是爱情
就像来不及许愿的流星
再怎么美丽也只能是曾经

太美的承诺因为太年轻
但亲爱的那并不是爱情
就像是精灵住错了森林
那爱情错的很透明

Should you invest £2 a day or use it to buy lottery tickets?
Maths makes the decision obvious. Suppose you invest two quid every day at the reasonable rate of 10%. It will take you almost exactly 50 years to accumulate £1m. To earn this same £1m in the National Lottery, you would (on average) have to match five numbers and a bonus ball, at odds of 2,330,635-to-1.
If you spent two quid a day for 50 years you would total just over 36,500 tickets and would thus have only a 1-in-63 chance of making that million pounds. However, the available image of immediate wealth subverts this rationality.

At your local pub, you have many beers to choose from. Which is best? If you are like most human beings, the answer is "the most expensive one." A number of studies have shown that by switching price tags, you can switch preferences (for obvious reasons, this is a favourite experiment among university psychology students).

And what about the power of suggestion?
Imagine I handed you a cup of hot coffee and then asked your opinion about a person whom you had recently met; now suppose I instead handed you a cup of ice-cold soda. Experiments show that your opinion of this person would be different because you have been primed to feel warmth or coldness.

Add to the list...
framing (how you present data is as important as the data itself)
impact bias (overestimation of possible outcomes),
confirmation bias (recognising only data that supports your hypothesis)
loss aversion (we stand to gain more than we would lose, but our fear of loss prevents us)
selective perception (seeing what you want to see),and
rosy retrospection (integral to the repeated experience of family Christmas)
...and you seem doomed to blunder through life led by your brain's clumsy irrationality.
