I can’t save everyone.  Ultimately, I don’t think I can save anybody—everyone die, sooner or later—but there are better and worse ways to go.

I saw pretty early that I wouldn’t really be able to do much with my talent as a doctor, which was my first thought.  There woludn’t be much changing lives—mostly people would only come in for problems they already knew they had, and any human doctor can give decent odds on how a person would make out—I’d just be better at it.

Instead, I volunteered to work with the homeless.
