What should I do when I can't remember a word I know?

It's a word I've known for a while, but sometimes I can't remember it.

A few days ago, while taking a walk, I saw a small stage next to the park.

So I

I performed a small concert there last time, didn't I?

Oh, what was it? I can't remember the word.

There's a free performance on the street.

I can picture the scene of the performance, but I can't think of the words~

No matter how many times I think about it, I just can't remember the word.

Are you talking about busking?

So, busking!! I understood when I listened.

 

The problem is that this has happened more than once.

Brain function is good until your twenties.

It is said that brain function declines starting in your 30s.

As I get older, it seems to get worse, and I also develop forgetfulness.

When nutrients enter the body, they are distributed for more efficient use, but if the brain is not used much, the amount of nutrients allocated to the brain is reduced.

It means that the cells that used to remember that word have lost their function, which is why I can't remember the word.ㅠ

The more such words there are, the more brain function declines.

 

Are there people like me who sometimes can't remember difficult words and experience forgetfulness?

Since the brain gradually loses function if not used consciously, I think it's good to provide various stimuli. What efforts would be beneficial for brain health?

Is there a way to improve memory?
