We thought this "double" in sport was the perfect idea for this week's top 10. So we asked our junior reporters what their favourite double moment is ...
A doppelganger - it basically means there's a person out there who looks exactly like you - is probably my favourite double. It fascinates me to stumble upon a person bearing a close resemblance to someone I know, even though the two can be completely unrelated and lead separate lives.
2. Double spirituality
Most people may think the Old and New Testaments of the Bible are separate. Yet a mind-shattering documentary shows otherwise. It says the Ark of the Covenant, an important and long-lost item in the Old Testament, is found right underneath the very spot where Jesus Christ, mentioned in the New Testament, died.
When I see "double A" batteries - that's how I can bring my Gameboy back to life and finish off my Pokemon Yellow game.
4. Double sausages
I used to get excited when I ordered a double Sausage McMuffin at McDonald's. It is simply satisfying and delicious, and there's no delicacy like it. Unfortunately, McDonald's doesn't offer it any more.
5. Acts of kindness
I like it when a person does something good, and life rewards them with a kind action from a stranger. Double good deeds - wonderful.
6. Choc-chocolate cake
Double-chocolate cake is what I love. Imagine the double-layered sweet sensation, with extra icing melting in your mouth. Mmm ... delicious!
I have to say twins, especially the funny ones. They can double the laughter!
8. Double scoops
Double-scooped ice cream makes me feel over the moon. What can be jollier than having double quantities of delight? Many of you will no doubt have the same amazing idea.
9. Happiness jackpot
As the old Chinese saying goes: "Happiness can be doubled by sharing it with another person." I am glad to see happiness doubled when my friends share something with me that makes them happy.
10. Day and night
The most amazing double is to see both the moon and sun hanging in the sky simultaneously. I witnessed this once while watching the sunrise in Australia very early in the morning. It really makes you wonder which celestial body is in the wrong place at the wrong time.
School starts again for some on Monday. To get a head start, you need to set your goals and execute; otherwise, you'll be lost and puzzled halfway into the new year.
For next week's top 10, Young Post would like to know your new school year's resolution. Send your entries, with your name, to email@example.com, with "top10_resolution" in the subject field.
