What is the highest number man has counted to?

I cannot speak for other men, but I can speak for myself. I am currently just about to count past ten million. I have counted up to 9,986,048, so far (not in decimal, though - I am stating the number, however, in decimal, because I know that that is the predominantly understood format). If anyone has counted higher than this, I tip my hat to them; because counting as far as I have has been one of the most demanding tests of my determination.

Sincerely,

Daniel

"Tuesday" - 8/28/2012 - Update: I finally counted past ten million, last "Saturday", the 25th day of this month.
