Something I have long suspected

I am glad to see that innovative researchers are extending boundaries
and challenging the status quo. While acknowledge there are some
shortcomings to the research, I believe these are adequately addressed.

I must say that as a rule of thumb I for many years have made a point
of associating with happy people. I beleive that in the process I have
'learnt' to be happy. Here is a selection issue to consider in the
construction of the network.

Obviously happiness is a two way street - it comes from within and
without - and the happiness of our friends and family is one component.

Fantastic article. I wonder whether this type of analysis can be
linked to findings in 'happiness economics' that have shown that after
'happiness shocks' people tend to return to a constant state of happiness.
Are new happy friends a happiness shock?
