Do you guys have experience of what they call brain fog?

It's a situation where your mental clarity is not what it is used to be and you're not as sharp as before.

I'm noticing this for myself where I find it hard to remember certain names, words, phrases that I know is just at the back of my head. I just know that my mental clarity is not working at 100%.

For example, was talking with some friends on some gory movies, and I remember very vividly the scene where this person was sawing his own hand to escape. Unfortunately I couldn't remember the title of the movie.(It's SAW after goggling it)
Another example, wanting to send an email to one of my colleague, but I couldn't remember her name despite just talking to her just last week.

Anyone of you experiencing this ? What did you do to overcome this?
