1 year? I doubt you could reach 100 million.

There are 31.5 million seconds in a year. 
You’d need to sleep about 1/3 of that, so you’d be awake for 21 million seconds in a year. 

Counting anything beyond 1,000 begins to slow down as you say “one thousand ....” before the rest of the number. At “one million...” we see another jump in the periodicity. 

Realistically, I’d be shocked if anyone could count to 10 million in a single year.
