exploration

     There are a ton of ways people have explored over the years. One of the most famous of course being Christopher Columbus while of course it was an accident. Another exploration of the unknown over the years is Thomas Edison while exploring new idea in science it was not exactly physical. It was more exploration in the mental field.

     People have devoted themselves to exploration because for one humans have a natural right to curiosity. other then that we just need to advance ourselves. 

     Some sacrifices were with families. Like, the explorer spent so much time on what they were exploring then their families have to move on. Or they even make physical sacrifices suck as death or even an ear.
