Is the glass half empty or half full?

Many people aren't optomistic enough these days, maybe its because there isn't as much to be optomistic about these days. I believe in almost any situation a positive light can be shed onto it. And maybe it is human nature but people dwell on negative situations longer than they hold a positive feeling for.

I am a very optomistic and postive person. Even in the worst situations I can find humour or a positive side.

It has actually been proven that optomistic people outlive and are healthier in general than pessimistic people. It's sort of obvious though (this is not a random 82.422% of on the spot facts).
