      Hi, great Q, what age are you?
      If you’re about 10years of age you have about 10 million million red cells in your body, or in other words 10 trillion, that’s a lot!!!

      Red blood cells typically live for about 120 days before they die and are replaced by new ones. Red blood cells are made inside your bones, in the bone marrow, but don’t worry they don’t all die at the same time! Your body is constantly making new ones as the old ones die.
