To anyone confused, they're referring to "if true love is one in a million there would still be 7000 people in the world you could be in true love with"
This was back when there were merely 7 billion people on Earth
I remember when it hit 6 billion. It's wild that population was below 5bil when I was born and its over 8bil now. Barring any catastrophic events (either personal or global), I'll be seeing world population double within my lifetime.
