There comes a time when every single bit of energy and patience--mostly patience--is drained from one's body.
There's a scene in an old movie, Jason and the Argonauts, when on the island of Talos, the giant awakens when someone takes a javelin (actually a pin from a broach) from a tomb/temple. Talos is one of the Titans, only he is a giant bronze statue on top of the tomb.
The men from the Argos have been warned not to take anything but food and water from the island. So, when one of the dudes, I believe it is Herakles, walks off with this pin he thinks to use as a javelin, the mighty giant comes to some sort of bronze life and goes after the guys from the ship.
Jason--mind you, he's a sort of hero in charge of the search for the Golden Fleece--realizes he can't fight the statue which towers over everyone and everything. But he's clever. He's been told by Hera to look to the giant's ankles. No, this isn't about Achilles, though we all know what was wrong with his ankles. This is about Jason and his need to defeat the bronze Ray Harryheusen Titan.
He scrambles between Talos's bronze sandals and sees a round screw-in plug. After great grunting and exertion, Jason opens up the plug and out pours a river of reddish goo. This stuff is what has powered the living statue and eventually, once it is drained sufficiently, the statue crashes and becomes immobile. The remaining crew of the Argos get back on the ship, except for one young fellow.
Herakles, feeling bad that it was his fault the giant awakened and the rampage happens and this one young guy is missing, decides to remain on the island and search for the kid, thus leaving the crew to carry on to Colcos for the fleece.
Down one hero.
But what I'm referring to mostly is how the huge, mighty bronze colossus gets all the goo drained from it and becomes immobile.
That's me. I am Talos.
I think I need some alone time.
