I just like snakes. Heck, I like all animals. I have had several pet snakes, most of them corn snakes, which are closely related to rat snakes. And I know how docile both snakes are, and the benefits they provide to farmers. Snakes are beautiful creatures IMO. Once you hold a snake and feel that incredible muscle mass, you are immediately fascinated. I doubt that corn snakes are seeking social interaction, I'm imagining it's our warmth that they like, but I know that they'll happily set loosely coiled around my neck for hours, and I love that. I have held tiny baby snakes, and I have helped hold a 22' reticulated python. I've had no fear of either. I have accidentally gotten close to rattlesnakes, luckily not too close. If you respect their space, there's no reason to fear them either. Though I wouldn't try to interact with a poisonous snake.
Had I not known my love for woodworking early on, I could see myself in the zoology field.
