When I get blue about the foibles of our species, I think of all the trillions of processes that do their job perfectly day in and day out to keep us in the here and now, even when we are “sick.”
Witness the beauty of the electron transport system in every one of the thousands of mitochondria in each of our trillions of cells—which, by the way, started from just one cell.

At death, when these little turbines cease their work, I think of all those protons, electrons and neutrons going back out into the universe from whence they came. Isn’t this “immortality” enough?
