Cool to be kind: being nice is good for us – so why don’t we all do it?

As science proves that acts of kindness benefit both giver and receiver, we ask why some people are so much better at putting others first

It was freezing cold the day Neil Laybourn saw a man in a T-shirt sitting on a high ledge on Waterloo Bridge and made a split-second decision that would change both their lives for ever. It's hard to pin down what it was that made me stop... but it would have played on my mind if I hadn't," he said. That's not how you live your life is it? You don't just walk past when you see someone in need."

On that January morning in London's rush hour, hundreds of other people were doing exactly that. But Laybourn didn't and - it turned out the man, Jonny Benjamin, was contemplating suicide. Six years later he would launch a campaign to find and thank Laybourn for persuading him down off that ledge. The two of them now give talks on mental health issues and suicide prevention together.
