Would it just be restricted to animals? Because I can think of a lot of other things I would rather choose to be if I could permanently change my form. It'd be nice to shed the social weight and stigma behind such ridiculously loaded subjects as race, gender, age and all their attendant nonsenses by becoming a living humanoid object. I mean, honestly, who is going to bother a trumpet peron, a sunflower person or a telescope person about that stuff? That'd be like berating a lamp for not looking -insert anything here- enough. Humans are kind of odd, they find the weirdest things to nitpick and don't let the subject die until the theoretical horse has been beaten ad nauseum. How many theoretical horses have valiantly subjected themselves to this rubbish? When will we take a stand against such flagrant abuse of imaginary equines? *Shakes fist.* That said, it'd have to be a pretty perfect world for something like that to happen and not severely alter your life. If we know anything about humans, it's that in a general sense, they tend to fear things they don't understand. There's a good chance one could end up getting hunted down for suddenly appearing quite not-human. If I knew that life could continue on largely unchanged, I may go for it. But otherwise, I don't think the benefits would outweigh the drawbacks of giving up a human shape. Additionally, even if everything went smooth as silk, there's also a chance you might find you don't actually like the form you've chosen. There might be unforeseen consequences to the change that you didn't realize or couldn't have predicted. Or, you might just miss how you used to look because it's what you know. I can imagine it would feel rather strange to wake up in the morning, go to look at your reflection and not recognize the creature you see in the mirror. You'd get used to it, of course, but there would definitely be some vast differences. -Edit- Also if you chose to be a really fluffy animal like, say, a fox- can you imagine how much shampoo you'd go through!? And you'd probably have to invest in a lot of lint rollers.
