You don't know what you've got till it's gone

I went through the last few days feeling pretty sick. I was lightheaded, feverish, and achy. What struck me is how bad I felt and how hard it was to do everyday life.

I forget so quickly how much my life depends on complicated processes that go on in my body. Each system plays into the whole and the whole is indebted to the system. When systems break down, life becomes so much more complicated.

When I feel good I so easily forget those systems, and expect life to continue forever. The sad reality is that it doesn’t. But that doesn’t seem to stop my fantasy about my own invincibility.
