We use our memories to imagine the future

Past experience, which many experts think helps them to better understand the world, surprisingly does not improve the ability to predict the future. The research data showed accuracy levels of the younger generation (25 to 35 years of age) being the highest.

Old people are slower to comprehend change, faster to believe and share fake news and less likely to be objective.

Working with an open mind, ready to dive into unfamiliar territory and learning new things, makes the entire exercise stress-free and rewarding experience. This state of mind, along with basic humility makes for better performance. One’s arrogance, ego and past can negatively affect the prediction quality.

A humble attitude also makes people listen to others opinions and share their own unique insights, helping collaboration and constructive teamwork.

Most of us forget more than we remember. We change memories to make sense of what has happened in our lives. When we then recall a memory, we reconstruct the events in our minds and even shape them to fit in with any new information.

Many of us think of our past as a kind of a video library where we can look at records of our lives. If memories were fixed like videotapes, you would find it difficult to imagine a new situation.

It is our past memories that help us imagine a future, and to preview future events. This skill of using the past to predict the future helps us try out different hypothetical scenarios before we commit.

Aphantasia was first described in the early 1800s by Francis Galton in a paper on mental imagery. It was not until 2015 that the phenomenon was further studied and the term was coined.

One of the major studies was with a patient who had undergone a minor surgery in 2005 and later could no longer generate visual images within the ‘mind’s eye’. The details of the study were published in 2010, which led to many others coming up with similar symptoms.

This was a technique used by the researchers to help test the image forming inside the brain of the individuals.

The experiment led to the finding that a recent viewing of an image had no correlation with the imagining of the image.

Swiss physician Johannes Hofer referred to nostalgia as a kind of homesickness, a desire to return to the beautiful, simpler times.

The feelings of nostalgia were usually melancholia, anxiety, and rumination. It was made into a neurological illness, which was related to the geographical location of the person longing for home.

• Nostalgia was considered by the early 20th century a psychiatric illness caused by some traumatic experience of childhood. It had three components, cognitive, affective and conative.
• The cognitive part remembered old memories of the self, while the affective part was a sad emotion, finally moving towards a desire to return home(conative).
• Nostalgia is neither a pathological state and nor is it necessarily beneficial. What we can think, remember or imagine, is not bound to be real or factual.

The best things in life will most likely be hard, and if you spend your life avoiding discomfort, you’ll miss out.

One of the most important skills you can develop is being okay with a degree of discomfort. If you get good at this, you can do anything.

If you can accept uncertainty, you’ll be open to many more opportunities.

If you’re afraid of uncertainty, you’ll skip starting a business, for example. You can’t really know for sure how things will turn out, and so if you have this need to control the outcome, you’ll avoid great opportunities.

• Declarative (or Semantic) memory is our factual memory which stores the details like the information and figures, but not the visual, emotional or sensory details.
• Episodic Memory stores our life events, for us to be able to relive our past, complete with all the atmospheric details.
• Procedural Memory is the memory of skills, in which the brain records the sensory input from the various body parts and muscles during a particular activity, and is able to replicate the muscle application and movement.

It is the area of the brain responsible for learning new skills.

Using brain mapping tools, scientists have discovered that the more we use a certain body part, the more information about it is stored in the Primary Motor Cortex region of the brain, which alters its size and the number of connections with the other regions of the brain.

The most fundamental aspects of nature stay the same.

For example, Einstein's papers on relativity show that the relationship between energy and mass is invariant, even though energy and mass can take on many different forms.

Even though matter produces energy, the energy-matter content of the universe never changes. Matter and energy are less fundamental than the underlying relationship between them.

We often think of things as the heart of reality. But most often the relationship is more important, not the stuff.

We may think "stuff" like space and time are unchangeable aspects of nature. In reality, the relationship between space and time stays the same.

Humans are different from animals in that we don't sense time only as passing. We dice time into units or think of time to go beyond our lifespan, such as millennia. We rely on time concepts that allow us to make plans, follow recipes, and discuss possible futures.

Recent research suggests that across all cultures, the concept of time depends on metaphor, known as a conceptual metaphor. We build our understanding of duration and sequences of events out of familiar spatial ideas such as size, movement, and location.

But the "time is like space" metaphor takes on very different forms from one culture to the next.

• Internal memory cues are patterns of thinking that help trigger a specific memory. For example, mental imagery, which involves visualizing a certain scene happening, can serve as an internal reminder of an event that happened.
• External memory cues are objects or events that trigger a memory that they are associated with. For example, a glass of water next to your bed is an external reminder to drink water when you wake up.

• To remember to floss your teeth, put the box with the floss on top of your tube of toothpaste.
• To remember to take a pill each morning, put the pills next to whatever you usually eat for breakfast.
• To start the day by writing, put a piece of paper with a reminder on top of your keyboard.
• You can use your watch as a reminder to take things easy, so that every time you look at it you remember to relax a little.
