I was looking for the source of the phrase “The way to
live the longest is to acquire a chronic disease and take good care of it." I found that attributed to Sir William Osler in 1901. I also found it quoted as: "The way to longevity is to develop a chronic disease early in life and learn to live with it" and as “If you develop a chronic illness and take the best possible care of it, you will live a longer and healthier life than those who do not have that advantage.”
In that search I came across a fascinating speech by Mark Vonnegut (son of Kurt) reflecting on mental illness. After several serious psychotic episodes he became a pediatrician.
