A morcellator is a surgical instrument used for division and removal of large masses of tissues during laparoscopic surgery. In laparoscopic hysterectomy the uterus is minced up, or morcellated, into smaller pieces inside the woman's belly cavity in order to extract from the abdomen.
What disease does Steven Hawking suffer from? He has a muscular dystrophy cognate to amyotrophic lateral sclerosis (ALS), the latter being also known as Lou Gehrig's disease. Edit
He doesn't have ALS but rather another form of neuro-muscular dystrophy related to it. I wouldn't exactly call him lucky - he is completely paralyzed except for his eyes. Hawking is definitely more famous than he probably would be if he didn't have his condition, but he is still very smart. He's done a lot of work with singularities and black holes, and discovered that black holes actually aren't completely black. The type of radiation they give off is called Hawking Radiation.
