Interesting fact:

There are now over 7.4 billion people on earth – and that’s with 1.8 billion of us being between the ages of 10 and 24! That’s the largest population of young people to ever have existed. 52% of the total world population is under 30. And the ‘average person’? A 28 year-old Han right-handed Han Chinese male – there are nine billion in the world right now.
