Here are some fascinating facts :

1. 1 sperm has 37.5MB of DNA information in it. That means a normal ejaculation represents a data transfer of 1587GB in about 3 seconds !!

2. The focusing muscles of the eyes move around 100,000 times a day. To give your leg muscles the same workout, you would need to walk 80km (50 miles) every day.

3. The longest internal organ is the small intestine. Despite being called the smaller of the two intestines, your small intestine is actually four times as long as the average adult is tall. If it weren’t looped back and forth upon itself it wouldn’t fit inside the abdominal cavity.

PREGNANCY.

When a friend of mine got pregnant we talked a lot about babies and as well as pregnancy itself. We googled some mind-blowing facts I would like to mention (some were quite fascinating ;)):

1. During pregnancy the uterus stretches from the size of a peach to the size of a medium watermelon.

2. A woman’s placenta from a pregnant woman can produce more estrogen in one day than a non-pregnant woman in three years.

3. The possibility of multiple birth will increase with tall or overweight mothers.

4. In 90% of the cases skin tone will change during pregnancy.

5. Pregnant women and new mothers can lactate when a baby is crying – even if it’s not their child.

6. Pregnant women develop an enhanced sense of smell. Thereby she can avoid food which may be harmful to the baby.

7. Nearly 75% of all conceptions miscarry. That means most women have been pregnant at some point in their life. A miscarriage can happen without knowing it. It happens just like a normal period.

8. In the second half of pregnancy, the baby will urinate about a liter per day. After they drink it. Baby’s fingerprints are formed in the first three months of pregnancy.

9. Babies cry in the womb for practicing for their big day :)

10. Babies are able to crawl immediately after birth. Therefore a baby can crawl on mom’s chest and find food (breast milk).

11. Newborns are quite strong. A newborn can grasp so strong that it would be able to hold its whole body with its fingers.

12. Newborns do not have the ability to swim – but they have reflexes that make it look like they can swim.

13. Newborns also have another reflex, which is called the bradycardic. That makes babies hold their breath and open their eyes when submerging in water.

14. Newborns kneecaps are made out of cartilage (like shark bones!). After a while it converts to bones.
