They say twins can be double trouble, but triplets are thrice as nice. It wouldn't be hard to believe after seeing these adorable triplets playing with their dad. The study of twins, triplets, and other multiple births is known as Gemellology, 'gemello' being Latin for twins. Scientists suspect that the rate of conception of twins/multiples is actually much higher than the birth rate for such individuals, the theory being that the other multiples might be absorbed in the womb by the most dominant child. Twins are naturally very connected, with many twins/multiples creating their own secret languages, and identical twins have been found to display identical brain waves.
