Nostalgia
Nostalgia is an emotion. It is the feeling of enjoying events from the past. People with nostalgia will often look at or use old things that they were familiar with years ago. This is because people feel more connected to those past times that they enjoyed, usually because it reminds them of how long it has been since they last connected to such past times. Examples where people may have the feeling of nostalgia includes watching old TV shows, using old technology that was very enjoyable, and playing with toys that you played with as a child. These memories are usually misleading, and can make someone wish that they could be young again, even if their childhood was mediocre. Human brains often leave out boring or bad memories, which can cause incorrect feelings about their childhood.
