Have you ever had this feeling?

Today my brain wasn't working 100%. Maybe around 85%? But for sure not 100%. I was stumbling on normal tasks, like spelling and typing.

This might be a mild form of that brain fog I had a while back now. I haven't felt that in a long time.

But, all in all, i do feel betterer. I wish I could exercise, still might not be ready for that yet.
