Document Summary
If you get sick from virus x today, you won"t get sick from it again later. Incidences of colds decrease with age, as growing up, you are exposed to different kinds of viruses to become resilient towards them. As you age, your body weakens, and that scarring carries on throughout your life. These generate an immunity without the sickness, and the memory of an infection without getting the infection occurs, and you will not be affected later on. Impossible to know beforehand what will infect you. Recognition of microbes based on large number of random molecules (antibodies and receptors) If a microbe infects once, it is likely to infect again. Once you find an antibody that works, it stores large numbers of copies. Therefore, you will not get sick a second time. Select" a molecule that works from a random collection. Creates copies of the units that work. It is used to get rid of the invaders.
