Would anyone like to hear the lecture I was planning to give on the subject above on Zoom. It's a personal story of my life as a Celtic Supporter and the science of how to learn to think like an Optimist. Scotland, like New Zealand is a very pessimistic country. It would take about an hour and I could give it if there was some interest. If interested just contact me at fisiani@gmail.com. I'd like to give it on Sunday 17th May 9pm Scotland time.
