Could it be that I did not figure in either the general nature or the permanence of the slowing, the irreversible changes in mind and body, the way in which you wake one summer morning less resilient than you were and by Christmas find your ability to mobilize gone, atrophied, no longer extant? The way in which you live most of your life in California, and then you don’t? The way in which your awareness of this passing time—this permanent slowing, this vanishing resilience—multiplies, metastasizes, becomes your very life?
