Self-preservation

A drowning man would catch at razors.Italian.

As sore fights the wren as the crane. (All are equally courageous in extremity.)

He that is carried down the torrent catcheth at everything.

He that is drowning shouts though he be not heard.Italian.

Self-preservation is the first law of nature.
