Keeping busy: The young man had snacks and water to keep him going but said he didn't know how he would go to the bathroom

The rules were as follows: Mr Hobbs had to keep is finger on the down arrow key for as long as it took to reach the last row in Excel.

He had food, water and energy drinks, but said he didn't know how he was going to use the bathroom.

Mr Hobbs even recorded the feat, uploading the footage to YouTube in a time lapse.
