I think I'm in the same boat, always been interested in that specific field and 19 years later I'm in my third year of my marine biology course and going on to do honors next year. Yes a lot of people think its all dolphins and whales then get disappointed, but there is more to marine biology. All the amazing creatures which are out there captivated me from a young age and now with processes changing finding out what is happening is really interesting.

Yes, yes it is awesome.
