Have a little think about all the strange thoughts that enter your mind when you're trying to fall asleep. At moments like these, particularly when you want to fall asleep quickly, your brain starts bringing up weird questions, such as 'How much does a cloud weigh?' or 'Can I smell things while I'm asleep?' Luckily, we've got the answers to both of these questions and more!
Here are 18 facts that you won't be forgetting anytime soon:
1. People born in the 90s have lived through three decades, 2 centuries, and 2 millennia, and they're not even 30 yet!

4. In your lifetime, you'll meet around 16 murderers without even realizing it.
5. You can work out how many days each month has by using your knuckles. Simply make a fist, and count the months by using your knuckles and the gaps in between them. Each knuckle is a month with 31 days, and each gap contains 30 or less. Once you reach the last knuckle of one fist, move on to the first knuckle of the other one, so that July and August are both counted on knuckles.
6. In a single day, your heart makes enough energy for a 19-mile truck trip.

16. By the time you reach 60, you will have lost around half of your taste buds.
17. The carbon all of us, and indeed, all living things, are made of - was created inside stars, because only the fierce furnace of the sun could create this heavier element out of the lighter elements like hydrogen.
