Who takes his eye from a comet?

Brigid emails to say that Tin Can Assassin is back in the hospital with heart problems.  This is the second time this has happened, which isn't ever good. He has a donate button up on his site, if you can spare something for one of our fellows in this corner of the Internet.

Who casts not up his eye to the sun when it rises?  But who takes off his eye from a comet, when that breaks out? who bends not his ear to any bell, which upon any occasion rings?  But who can remove it from that bell, which is passing a piece of himself out of this world?

No man is an island,  entire of itself; every man is a piece of the continent, a part of the main; if a clod be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a manor of thy friend's or of thine own were;  any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bell tolls; it tolls for thee.

- John Donne, Meditation XVII
