Health IT helps save lives now lost due to preventable medical errors, from incorrect diagnoses and needless infections to drug mix-ups and surgical mishaps.

We're all essentially surgically connected to our smartphones, and we're still in the early stages of realizing their medical potential. But they should be a real threat to the medical profession.

Perhaps I will stay in Chicago and operate on human beings instead of on dogs. From a business standpoint, it would be excellent. But, as I hate medical practice, I would like better to make little money in doing scientific work than a great deal in doing surgical operations.

Medical need is an infinitely expandable concept. There is always one more marginal procedure that can be done. There is no end to the medical and surgical treatments that a technologically sophisticated and advanced society can give to aging bodies.

We basically built a pricing model that surgically identified what people wanted to pay us for and what they didn't want to pay us for. One of the things we figured out early on was that we could create value for people by creating a product that allowed them to design something that they couldn't design without us.

I should be happy, but instead I feel nothing. I feel a lot of nothing these days. I've cried a few times, but mostly I'm empty, as if whatever makes me feel and hurt and laugh and love has been surgically removed, leaving me hollowed out like a shell.

Desiring another person is perhaps the most risky endeavor of all. As soon as you want somebody-really want him-it is as though you have taken a surgical needle and sutured your happiness to the skin of that person, so that any separation will now cause a lacerating injury.

A molecular manufacturing technology will let us build molecular surgical tools and those tools will for the first time let us directly address the problems at the very root level.

Disease and ill health are caused largely by damage at the molecular and cellular level yet today's surgical tools are too large to deal with that kind of problem.

Over the years my mother's steadfast faith in God has inspired me particularly when I had to perform extremely difficult surgical procedures or when I found myself faced with my own medical scare.
