Building Bonds
Continuous interaction with the team members, working with them for the day, having your meals with them, sharing your joys and sorrows helps in building a strong bond between each other. In this way, you can even make friends for a lifetime.
Healthy Competition

Well this is possible when you work as a team, as everyone is emotionally bonded to each other.
