I find it kind of funny how in this age of humanity we look so much towards medicine for cures, that we forget the things we already have. In this case, will power is the subject. Anyone who says they can't battle addiction because it's a physical thing, well so is your brain, believe it or not. Buddhist monks can set themselves on fire in protest, sacrificing their lives, physically overcoming their primal instinct for survival for the betterment of the whole, but some people think they "can't" stop drinking.
The obvious wonders of the world are mostly discovered... Most of the wonders that are left can't be discovered by taking a walk or a long run, but they do still require a journey... It's still a journey that most people shun, that part hasn't changed. We search for the finer things... The things most will not believe are real until they're shown, just like most people didn't believe the world was round until someone showed them.
