Pain is weakness leaving the body.

Soccer players can do it for 90 minutes in all positions!

I think I'll be ready for that, ... I don't feel any more pain.

Some old wounds never truly heal, and bleed again at the slightest word.

Day followed day, and night followed night, until Dany knew she could not endure a moment longer. She would kill herself rather than go on, she decided one night...
Yet when she slept that night, she dreamt the dragon dream again. Viserys was not in it this time. There was only her and the dragon. Its scales were black as night, wet and slick with blood. Her blood, Dany sensed. Its eyes were pools of molten magma and when it opened its mouth, the flame came roaring out in a hot jet. She could hear it singing to her. She opened her arms to the fire, embraced it, let it swallow her whole, let it cleanse her and temper her and scour her clean. She could feel her flesh sear and blacken and slough away, could feel her blood boil and turn to steam, and yet there was no pain. She felt strong and new and fierce.
And the next day, strangely, she did not seem to hurt quite as much.

We go to hell to show everyone's pain. We all suffer severely at one time or another. But when you look at the whole world, there are so many people who are suffering much more than we are. It gives a great relativity to one's misfortune. You complain that 'I don't have everything I want,' and then you realize that maybe 20 percent of the world has clean drinking water.
