what is the population of the world?

Football League Cup Final 1970-71: Empire Stadium, Wembley (Att:- 100,000)
Tottenham Hotspur 2-0 Aston Villa

I remember it well - worst day of my life - I don't like football - but the memory of seeing 100,000 people for myself struck me.

So how many people are there in the world? Apparently 6.93 bn at the moment. I can't get my head around that many so I'm going to try another way.

One of my favourite expressions is "I am a grain of sugar in a very big bag", so my thought today is, how big is the bag?

I couldn't find a good photograph of the spurs vs villa match, but instead, I've a photo below of the Live Aid concert at the old Wembley stadium, 1985:

80,000 people.

So for each of the 80,000 at Wembley that day in 1985, including the ego of Bono, and the dubious justification for Bob Geldoff setting up the concert, I'm replacing each person with a grain of granulated sugar - sugar not sand. So the stadium becomes, for practical purposes, empty.
So now I pick up all the grains of sugar and "pour" the grains into a teaspoon.

About 2 heaped teaspoons, in fact, for 80,000 people**.

So how many people are in the world. Well there's the around 5 million people per bag of sugar (standard 1kilo bag of granulated). The world's population of 6.93 bn is in fact 1,386 bags, or 11 bags x 11 bags x 11 bags, giving us 1 huge bag of sugar! The human race:
