Just a question, but do all people have as much trouble putting one foot in front of the other like she did in the first 10 minutes? I'm not trying to make myself sound like the worlds greatest hiker, but I've never had a look of misery, like hers, on my face even at the times when I was most tired. But I've lost about 65 pounds, and I feel at my peak when it burns to breathe basically. I guess it's a pain-for-pleasure sorta thing, or even a high from knowing impossible is possible. It's very hard to put into words, but I love it.
Perhaps The actress was just over-acting and atempting to be dramatic, but I thought it was silly and lousy.
