Yup. I have blurred the last couple of years into one loooooong year and I frequently mix up dates on some projects I have been involved in. Then I realized some of them have spanned over a couple of years on and off so they are not attached to a single year in the brain log. With some fuzzy logic and some sifting through the phone pictures the veiling haze sometimes clear up...
It is only when you realize that "last years work" was three years ago that you start thinking a longer vacation would be a good idea.
