As we mature we do learn new things. The biggest thing, is learning ourselves. We are willing to experience things we never have before. When I was younger, I never wanted to try anything spicy. Now I love spicy things. My best friend threw a 37th birthday party for me, and he oysters there. Never had oysters before then. This is also a favorite food of mine.
Our minds expand beyond some of the things we weren't willing to try or learn. I think this is the beauty in maturing.
