[EX Q]: Consider this quote from Mark Twain: 'Familiarity breeds contempt - and children.' Does it mean having children is a bad thing? Could you explain what the children imply here?.
[EX A]: Two thoughts are run together: Familiarity breeds contempt {knowing people very well lets you see their faults} Familiarity breeds children {physical familiarity between the sexes leads to children} Hence Familiarity breeds contempt and children. A similar example of this particular way of playing with words (called Zeugma) is: 'You are free to execute your laws, and your citizens, as you see fit.'

[EX Q]: For example In Sim Lim Square cheat cases, a person paid $1k for iPhone insurance. He 'agreed' to buy it because the price was not clearly written. In some restaurants, prices are not written clearly and people can then be charged exorbitant prices. Insurance costs can vary by up to 100 times because the cost is simply not written clearly. Many politicians use deceptive language. Also, they tend to tell only the benefits without telling the negatives. Say you are a scientist. You have 10 studies supporting your theory and 90 studies showing you are wrong. You only quote the 10 studies to people that can't expect. All of these are deceptions that would make people choose really really 'bad deals'. Is there a word to describe such deceptions? Lying? Sophism? Fraud? Scam? Pull a fast one? What?.
[EX A]: Mislead/misleading One can be misled into thinking something, even if no lies are involved. Doesn't necessarily rule out lying though. The restaurant misled its customers by hiding information about extra charges

[EX Q]: Is there a single word in English to describe someone who is too worried about their health and even thinks they are sick, thus, taking frequent clinical tests or taking too much predictive medication,etc.
[EX A]:
The word is hypochondriac and they suffer from hypochondria. noun A person who is abnormally anxious about their health. [ODO] ODO also gives the explanation of using hypo- ('under') rather than hyper- ('over') which one might expect if someone is overly anxious about something: late Middle English: via late Latin from Greek hupokhondria, denoting the soft body area below the ribs, from hupo 'under' + khondros 'sternal cartilage'. Melancholy was originally thought to arise from the liver, gall bladder, spleen, etc..
