Age, positivity and negativity

In a previous blog I was wondering about the age-related evolution of conservatism and liberalism. Today it's about our tendencies to see our glass half-empty or half-full.

Is there an age-correlation between the two? I would tend to think that – as we become wiser – we let fear go off our system and evolve towards a more positive outlook. Is this just me or is it possible that this orientation is more genetic and more related to one's depressive tendencies than a trait that we have some control upon?

I'm not quite certain. Perhaps we should take the time to examine this question – as positively as we can!
