Hello peaches100: I experience some of this. In my case I think it is a mixture of free-floating anxiety & aging with a bit of "maleness" thrown in for good measure. (My wife talks to me all the time & I probably don't hear 50% of it!) I also do little things that don't make sense. The reason you don't have this experience at work may be that you are simply more focused.

I have also wondered, from time-to-time, if I might be experiencing the early stages of Alzheimer's or dementia. I mentioned this once to my pdoc. He pretty-much just dismissed it. But he suggested that if it was of concern to me I might want to have some neuropsych testing. This might be something you could consider as well.
