These idioms were used in the making of the the Movie Gladiator
Your assistance would be appreciated
1- The original is 'blood, sweat and tears', which is used when people are expected to sacrifice everything in a project for the common good. Churchill used it in WWII. As it's an action film, you get the blood and sweat, but no need to cry.
2- I think this is a play on 'flesh and blood', which mean immediate relatives. In the film you get the flesh and brains from the fighting.
