People through the ages have explored the unknown. I believe this is possible through imagination and determination. Many many people have devoted themselves into a life full of exploration and discovery. This is mainly because there are so many questions unanswered and "unknown". People who are willing to explore different things and subjects tend to make sacrifices. Some get caught up in their research and disoveries and tend to sacrifice time with family, or time with other jobs. They could come across great opportunities, but turn them down because they choose to keep exploring.
