Do you remember what you typed on here?

I look back at things I have typed on here and I don't remember them. It is like I am reading them anew. I think they sound quite good or better than I would say, but not recognise it as mine (without seeing the name). I suppose some stick if they are super memorable but this is very few.

I do this with emails too.  I seem to have a fairly short memory window. I have full details for a short while then it goes. It has always been like this.

I am not sure if it is normal or not, or indicative of something else.
