An interesting research project by the non-proft group TED (Ideas Worth Spreading) resulted in some very unique results, especially in regards to the old axiom, money can't buy you happiness. In the video piece below, TED shows that in fact, using money in ways other than spending it on yourself in the accumulation of material goods, can in fact provide great happines and joy by triggering certain psychokinetic and physcially based processes which are the core happiness centers in the body.
In the end, it is a scientific look at what people throughout time and history have known. It is better to give than to receive, and happiness is derived best when you are both economically able to give, and when you are able to share what you have with others who do not.
The important thing as well, is the CHOICE to share, not the mandate of government to take from you and give to whom they see fit. That in fact, will bring you anger and bitterness versus happiness.
