Ten Years of Harry Potter?

I was very excited to read an article this morning listing the release date for the next Harry Potter book as July 21st.

Then I read that it will be the ten-year anniversary of the release of the first book.

Ten years?!?!?!?

I feel so old. I would rather not measure my age using book releases, but I'm really stuck on this one. It kind of takes away from the excitement of the last book in the series coming out. Oh, well. Still looking forward to reading it.
