One of the challenges of being older is to stay optimistic about life when long experience of people's rampant nastiness and stupidity can easily lead to engrained cynicism.After 62 years of watching relentless violence, carnage, greed and selfishness, it would be easy to conclude that humanity is doomed and expecting anything better is just self-delusion.
But despite everything I remain a stubborn optimist still convinced that if enough people saw the futility of their behaviour and changed course, the world could still turn into a better and more civilised place than it is right now.
It's completely irrational, I know, to think like this when every day the media are reporting new atrocities and depravities and millions are dying of preventable illnesses, but history is full of irrational people who believed in something that on the face of it was utterly impossible.
Yes, on the one hand I think of the tens of thousands who have died unnecessarily in Iraq. But five minutes later I think of the invention of antibiotics, the ending of apartheid in South Africa, or the arrival of electricity.
For every example of wanton destruction, there's another example of inspired creativity or selfless compassion, much of it hidden from view because the news headlines are dominated by tragedy and horror.
In my own life I can think of people who have unstintingly cared for those with disabling illnesses, people who have worked tirelessly to improve their local communities, or people who have battled fearlessly against prejudice and corruption.
I refuse to believe human beings are so degenerate they can only end up wiping themselves from the face of the planet. People have predicted that many times before but they were always wrong.
