This is such a beautiful answer. Being able to experience all of humanity like that is tough to pass up, but I'm often drawn to the animal power. You'd be the best biologist on the planet for every species, able to unlock secrets about the natural world we've never known the answer to (although, I doubt the conversation would be nearly as dense as a human conversation). From a practical perspective, you could become like the animal kingdom's Lenin, encouraging the liberation of animals used by the police and military and teach factory farm animals how to escape their confinements and overthrow their masters (which can't possibly backfire, right?). Or at the very least you could get a bunch of birds to shit on Elon Musk 24/7 lol.
