Black pudding, when I was a kid. Didn't 'like' it despite never having tasted it. Challenged by mother to try a bit. Loved it. When I was a adult, it was flying. I was scared until at the age of 42 I was persuaded to fly to Nice. I was nervous right up until the plane started rushing along the runway to take off. It was amazing, like being in a racing car or on a powerful motorbike. Fear cured, instant convert.
