Think you know all about twins? Check your knowledge against this list of fascinating facts about twins.
- A higher rate of twins (18-22%) are left handed compared to non-twins (10%).
- Identical twins exhibit almost identical brain wave patterns.
- Twins sometimes have their own language which only they can understand, this is called cryptophasia.
- If the mother is herself a fraternal twin, the chances of having twins increases about five-fold.
- Identical twins are sometimes born as mirror-image twins, meaning they are identical but their traits are reversed. For instance a left-handed twin would have a right-handed mirror-image twin.
- Without the assistance of fertility treatments, twins occur naturally in 1 out of 80 births; triplets in 1 out of 8000; quadruplets in 1 out of 700,000; and quintuplets in 1 out of 65,610,000.
- It is possible for fraternal twins to be conceived by two different fathers, a process known as super fecundation.
- The scientific study of twins is known as "gemellology."
- Twins do not have to be born on the same dates. The longest gap between birth is 85 days.
- Once you've had fraternal twins, you are 3 to 4 times more likely to have another set!

85 days! now that would be one heck of a labour! LOL
