As a completely biased Geography teacher - I'm with happygardening - I love my subject and constantly find it ways to be relevant to the students' lives that I teach.
Having said that my best advice to all my year 9 classes is to do the subject that you enjoy. That will be the one that you are more prepared to work at, that you won't mind sitting and doing extra work for while your mates are out somewhere and ultimately will be the one that you succeed in.
oh and you can always find something relevant to watch on the Eden channel and pretend it's revision.
