Twins: Pieter and Paulus Langerock from Belgium are the world's oldest twins and they were born before the first world war. They celebrated their 102nd birthday in July last year. When people enquired about the secret to their long life, this is what they had to say, " A glass of wine a day is our secret to long life". There are paternal twins and fraternal twins. Paternal twins are identical and fraternal twins don't have to be identical. It's nice to be born as a twin, you always have someone to look up to and care for, from childhood. Just because they are identical twins, they don't have to have the same kind of likes and dislikes. So if you are a new mom to twins, be ready to put in some extra work or get some help, since it's not an easy task to bring up twins or triplets or octulets.
