QUOTE : Of course the Curies died. They identified ionizing radiation while bathing in it. There were risks involved in being your own guinea pig. But there was a long tradition of scientists doing just that: of paying for the expansion of human knowledge with their lives. I didn't deserve to be categorized with them, because honestly, I wasn't interested in the greater good. I just wanted to make myself better legs. I didn't mind other people benefiting in some long-term indirect way but it wasn't what motivated me. I felt guilty about this for a while. Every time a lab assistant looked at me with starstruck eyes, I felt I should confess: Look, I'm not being heroic. I'm just interested in seeing what I can do. Then it occured to me that maybe they all felt this way. All these great scientists who risked their themselves to bring light to darkness, maybe they weren't especially altruistic either. Maybe they were like me, seeing what they could do.
