How to help out the rest of the world question. (peace corp, type programs)?

[Matthew H]

So, i am sitting in my apartment on this friday night with my girlfriend and we are watching t.v. I come across one of those Feed the Children commercials and me, being the softy i am, cant help to stop and watch. I see these people on television helping feed these kids, help build schools, give medical assistance, etc. I was just wondering what do i have to do to be one of those people helping (like what program should i have to join). Im a freshman in college and have a goal that once i graduate, before i start looking for a job, i am going to travel the world for a few months and just see whats out there. But now, this commercial has got me thinking and now i want to spend that time going to like africa or asia and helping out those people. So my question is, should i join the peace corp or do they have like other programs that do stuff like that. I am not particularly religious but if you guys have info of like a christian program or something like that, i would love to...
know about them. Also, do i need to know a particular skill like medical stuff or anything. I am very good at health and nutrition stuff and i am a college kid so i can easily take classes. Do these programs want someone who specializes in something particualr. like i said, i just want to help in any way possible, (without just donating 8$ a month). I want directly help these people. i dont care if i dont get moeny or whatever and i know im not going to solve all the world problems with this, i just want to do little part in helping someone. any info on these programs and what these people do would be very helpful and i would be grateful . thanks
