Short attention span...

[LP]

Re: Short attention span…

so I guess the brain picks and chooses what to keep and what to throw away as something unimportant or insignificant?

Yes.This is what is happenning.

Do I have a seriously short attention span? bad memory, or just old age?

Do others experience this as well?

This has nothing to do with bad memory or old age.As you said,The brain picks & choses what to remember & what not to.
Yes.I experience it all the time.Mostly remember things which matter .
