Researchers found that two thirds of cancers are driven by random mistakes in cell division which are completely outside of our control.
It’s necessary not to starve to death, avoid being eaten by sabre toothed tigers, not get smallpox, for long enough for those multiplying cells to go wrong. Something is going to get you and the later whatever it is the more luck you’ve had.
