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.
