At 86 I am accelerating each day, learning about all manner of things from the bizarre to the mundane. This has been brought about by the amazing facilities online from Wikipedia to google and beyond. There is no excuse for ignorance any more, and curiosity is catching! Others may agree that the more is discovered or unearthed, the more aware one becomes of the depths of ignorance or lack of knowledge and this applies strongly to the bird world. There are so many unanswered questions. What a wonderful world.
