Why are we “the giraffes of altruism.”?

According to the neuro-scientist, Jonathan Haidt, humans are instinctively unselfish in some key respects. He sees altruism - acting for others rather than out of self-interest - as an evolutionary development. 

What's the evidence, Mr Haidt?There are signs that some forms of altruism are instinctive rather than learned. Even a very young child will come to you aid if you are struggling to open a door, for example. 

This suggests that an inclination to help others - is at least partially heritable. 

But isn't evolutionary theory based on the idea of the 'survival of the fittest'?Co-operation gives humans a competitive advantage over other species


But what's with the giraffe reference?The giraffe's long neck gives it an advantage over other species. Being nice - some of the time, anyway - is our equivalent of having a neck that gives you that extra bit of stretch when it comes to nabbing that fruit! 



BTW: giraffes & humans share the same number of neck vertebrae

What is an eysore? And a sight for sore eyes?

English can be a very confusing language.

An eyesore is something - typically a building - which is not pleasing to look at. This building is an example: 

A sight for sore eyes is the opposite - something is which aesthetically pleasing to the eye. This is often used as form of flattery e.g. you're a sight for sore eyes
What is the origin of eyesore?Shakespeare did not coin the phrase - though he is responsible for eyeball.  He did, however, provide an early example in The Taming of the Shrew, albeit one that is more metaphorical than is typical in modern English: 
Why, sir, you know this is your wedding-day:
First were we sad, fearing you would not come;
Now sadder, that you come so unprovided.
Fie, doff this habit, shame to your estate,
An eye-sore to our solemn festival!
And sight for sore eyes?First recorded example comes in another giant of literature: Jonathan Swift  in A complete collection of genteel and ingenious conversation, 1738:
"The Sight of you is good for sore Eyes.&quo…
