Essence

Biology teaches us that the central, most important part of a cell is its nucleus. It is where DNA is stored, and DNA is kind of what makes a cell function, as it is a set of rules, a history of activity and identity passed on and carried out for many generations. A cell, being the basic unit of life, is mastered over by the DNA in its nucleus.

And then you meet red blood cells. RBCs carry oxygen, and since they have to pass the tiniest blood vessels in our lungs, they have to be small enough, yet at the same time efficient. Hence in order to carry as much oxygen as it could while being able to squeeze through the tightest alveoli, a red blood cell loses its nuclues upon maturity.

I guess sometimes, we need to lose ourselves so that we could do what we are meant to do.
