Slightly loaded question...you presuppose that it does make people feel awesome! For some people it can be the scariest thing in the world. But if, like me(!), you are one of those folk who want to experience everything and learn more, then what better way can there be but by getting out there!
The sights, smells, heat (or cold) - the FEEL of a place - now that is living!
Your eyes opening, your senses expanding...the freedom to express yourself however you want; to ask questions; to try new things...the time to relish and soak up life...
What am I doing in front of a computer?? I'm getting out there! ;)
