On Friday, Bill Gates regained the title of the richest person in the world from Jeff Bezos, according to the Bloomberg Billionaires Index.
Gates' net worth is $110 billion.
In July, Gates was temporarily ranked as the world's third-richest person behind Jeff Bezos and LVMH's Bernard Arnault for the first time in at least seven years, according to the Bloomberg Billionaires Index.
While Gates indulges in a few luxuries, they make up only a fraction of his fortune.
