Doing the math without factoring in the amount of time it takes to say the higher numbers, it would take over 9,000 years to get to one trillion. If you’re counting in your head, the results won’t be much better. If you count in your head for 24 hours straight, you will reach somewhere around 600,000. One whole year nonstop would give you 220 million, and if you counted for your entire life, you would only reach the billions.
