Immune: A Journey Into the Mysterious System That Keeps You Alive

by Philipp Dettmer

Your Thymus basically begins shrinking and withering away when you are a small child. A process that is sped up once you reach puberty. Every year you are alive more and more Thymus cells turn into fat cells or just worthless tissue. The university closes more and more departments and gets worse as you age, until around the ripe age of eighty-five, your T Cell university closes its gates for good. Which is sort of horrible if you like the concept of being alive and healthy. There are other places in the body where T Cells can be educated, but for the most part from this point forward your immune system is more limited than before. Because once your Thymus is gone, you have to get by with the T Cells you have trained up to this point. The absence of the immune cell university is one of the most important reasons why seniors are much weaker and more susceptible to infectious diseases and cancer than younger people.
