Nostalgia is a psychological coping mechanism created from bias

Nostalgia is a psychological coping mechanism that can help combat loneliness—but it's created from bias

Researchers have observed that though nostalgia can help counteract feelings of loneliness, our memories of the past are somewhat rose colored. Negative emotions seem to fade faster than positive ones, a phenomenon that they suggest may be a psychological coping mechanism so that memories don't hurt every time they're recalled.

The "reminiscence bump" causes memories from adolescence to last

Learn about the neuroscience and psychology of why we crave comfort foods

The term was coined in 1966, when psychologist Joyce Brothers suggested humans turn to food associated with the feelings of comfort from their childhoods when experiencing emotional distress.

Retrieval cues can activate specific cells in a neural network, creating a cascade of neurons that collectively make up a memory. Specific cues help regulate emotions during stress by activating positive memories.

Memory is a complex narrative constructed from real and imagined experiences

How grudges mostly hurt ourselves

Grudges feel like revenge against those who have done us some wrong and are very common.

Friedrich Nietzsche theorized that we will live our lives over and over again: the myth of eternal recurrence

Rather than a theory of physics, the idea is designed as a moral argument. While Nietzsche famously eschewed the Christian afterlife, he wanted to avoid the nihilism that results from no longer having such an ultimate horizon. In a mystical moment, the philosopher came to believe that the fleeting moments of our lives would be repeated, presenting a test: would you want to relive this moment? If not, he would argue, you're not living well.

Clinical burnout: prolonged exhaustion, mental distance, and persistent negative feelings
