As Coach Howard said: "If you're not going to give me 110%, then keep your filthy hands off my rock." Ergo, those that give 110% have clean hands.
"But when the blast of war blows in our ears, Then imitate the action of the tiger;
Stiffen the sinews, summon up the blood...Now set the teeth and stretch the nostril wide,
Hold hard the breath and bend up every spirit to his full height"- William Shakespeare, "Henry V"
