This was not guilt: guilt is what you feel when you have done something wrong. What I felt was shame: I was what was wrong.

The battle of being mortal is the battle to maintain the integrity of one's life.

We have medicalized aging, and that experiment is failing us.

The big thing that's happened is, in the time since the Affordable Care Act has been going on, our medical science has been advancing. We have now genomic data. We have the power of big data about what your living patterns are, what's happening in your body. Even your smartphone can collect data about your walking or your pulse or other things that could be incredibly meaningful in being able to predict whether you have disease coming in the future and help avert those problems.

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.

Developing a skill is painful, though. It is difficult. And that's part of the satisfaction. You will only find meaning in what you struggle with. What you struggle to get good at next may not seem the exact right thing for you at first. With time and effort, however, you will discover new possibilities in yourself-an ability to solve problems, for instance, or to communicate, or to create beauty.

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.
