1. The human ear shape can be
used for identification with 99.6%
shape of the human auricle (the outer, visible part of the ear) is unique to
each individual. It represents a viable means of personal identification. While

invasive procedure, the shape of the ear is easy to map with computer software,
and rarely changes over a person's lifetime.

4.Children learn between 4000
to 12000 new words each year from reading books.
study showed that children can learn up to 12,000 words per year from reading
books alone. The average child will pick up around 2000-3000 words per year
from their normal education. This amount increases dramatically if the child
reads independently, even for as little as ten minutes per day.
5.Less than 5% of baby's are actually born on their due date.
Around 80% of women will go into labor between
weeks 37 and 42 of their pregnancy, but the majority of women will not give
birth on their exact due date. Knowing the due date is still important,
however, as doctors will use it to determine whether a fetus is developing on
