If I'm not mistaken, it was one year ago that Google introduced the Search History, and Phillip's post on it[1] seems to agree.
So, just out of curiosity, how many searches have you performed? I've made 9722 total searches. If I include the searches I've made at google.se it would be at least 10000 I think, about 27 per day.

My history shows 10,888 searches.
