No travel ban or quarantine will seal a country completely. Even if travel could be reduced by eighty per cent-itself a feat-models predict that new transmissions would be delayed only a few weeks. Worse, it would only drive an increase in the number of cases at the source. Health-care workers who have fallen ill would not be able to get out for treatment, and the international health personnel needed to quell the outbreak would no longer be able to go in.

The evidence is that people who enter hospice don't have shorter lives. In many cases they are longer.

When we lived in a society where we had large families that lived together, especially in agricultural societies like my grandfather and father grew up in, the result is you always had family around to take care of you.

Once you start to ask patients about their priorities, you discover what they're living for. Once you uncover that, it helps you, as a doctor, decide what to fight for. And when we do that, we often end up identifying limits to the kind of care that people want. One's assumption is that these people are going to live shorter lives, but what we're doing is protecting quality of life. In doing so, you sometimes end up helping people live longer. Certainly, you help people live better days and with more purpose in their lives.

Good checklists, on the other hand are precise. They are efficient, to the point, and easy to use even in the most difficult situations. They do not try to spell out everything--a checklist cannot fly a plane. Instead, they provide reminders of only the most critical and important steps--the ones that even the highly skilled professional using them could miss. Good checklists are, above all, practical.

You want to ensure people can do it right 99 percent of time. When we have to fire one of our surgical trainees, it is never because they dont have the physical skills but because they dont have the moral skills - to practise and admit failure.

You can't make a recipe for something as complicated as surgery. Instead, you can make a recipe for how to have a team that's prepared for the unexpected.
