Do you find spelling some easy words to be more difficult as you are getting older?

When I was growing up I was fantastic at spelling. If I saw a word one time, I had no problem recollecting how to spell it. Lately I find myself getting fustrated because I occasionally will forget how to spell a word. I, know it can be blamed on text speech (used on my phone) or even the laziness of using spell check, but I am beginning to wonder if its just a common thing as I age. Yesterday I had to look up how to spell pour. I knew it wasn’t poor or pore but I couldn’t remember for the life of me that it was pour.

And why is it I have an easier time remembering how to spell complex words but a harder time remembering the smaller ones?
