At different times, people have different points of view on their lifestyle and on the methods how they learn about the environmental world. Everyone stands for their own reasons, depending on their minds and wishes. For someone, it is important to be open to new experiences, and ready to discover, while for others it can be scary and uncomfortable. In my opinion, whether a person's preferences in their life do not expand any more, they have lost interest in life or they are scared by the unknown.
