Memories are a thing that everyone has. We remember emotions, food, place, people, trips and other things like that. I was thinking, “Why sometimes we remember an episode of life for years, and sometimes can’t remember 4 numbers for our password.”
Like everyone I also have memories. Sometimes I remember something for years, for long term, and sometimes I can't even remember anything for more than hour, for long term. This is what I found on the internet, how do some people say, “When we learn something—even as simple as someone's name—we form connections between neurons in the brain. These synapses create new circuits between nerve cells, essentially remapping the brain.” (“How Are Memories Formed?”) Which makes us remember different things. But some people say that we remember better when we feel a lot of emotions
What I also found is “Associative memories” “Associative memories, is a way how to remember better.” For example, you study for a test, but you can’t remember something, so you can smell gum or something else, and this makes an association between gum and what you remember for a test. On the next day, on a test you can smell it, and it reminds you of all what you studied. What experts think about it “Many studies have found a connection between odors and powerful memories. Scientists believe that smell and memory are so closely linked because the anatomy of the brain allows olfactory signals get to the limbic system very quickly” (Associative memory). This means that when we smell something, we are more likely to remember something.
In my experience, melodies can refresh old memories. For example, I have a few songs, which remind me of some memories from the past. This is what I found out about it. “Music evokes powerful emotions which bring back memories. When we listen to a piece of music from years ago, we seem to travel back to that moment. We can feel everything as if we were there. Our long-term memory can be divided into two distinct types, namely implicit memory and explicit memories.” “Why Does Music Bring Back Memories? What the Science Says.” And smells, when you smell it once and then smell it again you remember the first time how you smelled it.
   That was a long term\time memory, but now I will talk about short term memory. Short time memory is when a person can’t remember something for a long time. Different sources say different, but I found that short time memory is from 15 till 30 seconds. In my experience, short time memory happens when you try to remember numbers, pin code, password, phone number or presentation (Short-Term Memory). There are lots of reasons for a short time memory. Most common are getting old, head injury, infection, neurodegenerative disease, epilepsy and others. That was only a physical cause, but also there are some mental causes, like depression, PTSD, severe stress and substance abuse (Mayo clinic).
   In conclusion I want to say that if you train, your brain, not doing drugs, and not UFC player. You cannot fear problems with memory. Of course, memory will be worse in old age.
