And the numbers actually mean risk -- the higher the blood pressure, the greater the risk -- and the interesting thing is the risk begins to occur even at relatively normal blood pressure readings. So the higher you go, the worse off you're going to be, from a blood pressure point of view.
Hawking went on to Cambridge to research cosmology, the study of the universe as a whole. In early 1963, just shy of his 21st birthday, Hawking was diagnosed with motor neuron disease, more commonly known as Lou Gehrig's disease or amyotrophic lateral sclerosis (ALS). He was not expected to live more than two years. Completing his doctorate did not appear likely.
Amyotrophic lateral sclerosis (ALS), sometimes called Lou Gehrig's disease or classical motor neuron disease, is a rapidly progressive, invariably fatal neurological disease that attacks the nerve cells (neurons) responsible for controlling voluntary muscles.
