…We have a belly button 

Belly buttons have interesting origins! A foetus (growing baby) is attached to the mother in the womb by a tube called the umbilical cord. This cord is connected to the foetus’s belly. The cord supplies the growing baby with the nutrients it needs and also takes away waste products from the baby. Once the baby is born, it doesn’t have to be attached to the mother for nutrients any longer. Hence, the doctor cuts the cord but a small portion is left behind. This portion soon dries and falls off. Guess what is left? A belly button! 

…Pee is yellow 

The yellow colour in pee comes from a pigment (a naturally existing substance in our body that gives a certain colour) called urochrome. Our body renews red blood cells every day and removes old red blood cells. As the body breaks down these old blood cells, it holds back anything that’s useful and throws out the waste. Urochrome is one such waste product from the breakdown of red blood cells. The more liquids you drink, the lighter yellow your pee will be. An amber-coloured pee is a sign that you are dehydrated. If your pee is red, brown or orange, don’t panic but consult a doctor. Don’t forget to drink enough water! 

…We get a stitch sometimes when we run 

There are varied reasons behind getting a stitch or a catch in the side. Running increases the pressure and activity of the abdominal muscles. Sometimes they are pushed to do more than what they usually do and are stretched more than usual. This causes sudden pain in the muscle. A stitch can also occur when the ligaments (strong bands of tissue) supporting abdominal organs get irritated by movements. An increase in stress on your spine can also cause a stitch. But don’t worry, the pain doesn’t last long and can be prevented. Make sure you’re hydrated enough and you do warm-up exercises before you run.
