I'm a bird nerd because photographing marine fish is somehow more expensive than photographing dinosaurs.
I taught myself to write music a few years back, and then did the same thing with playing the flute, harmonica and didgeridoo.
Sharks are cool, too, I guess. I'm kinda landlocked right now though, so... you know. Limited relevance.
When I say "sharks are cool, too, I guess" what I really mean is that I literally have a degree in Marine Biology and am extremely bitter that I can't currently do anything with it.
