This is a childish question not related in anyway to prepping and reality obviously, but what the hell. I'd choose to be a killer whale. An apex predator with no real nature predators, smart, large and in charge with a wide variety of edibles to choose from and the ability to get far away in part from the worst population of animals on this planet, the human race.
I think I would be a bigfoot, which is obviously the ninja of the animal world.
I would walk around naked eating berries and nuts, leaving the occasional footprint and scaring the shit out of any hikers that I saw. I would chill in the secret bigfoot cave with my secret bigfoot homies, wiggling my unibrow at bigfoot chicks while saying, "Yeah baby, my feet are HUGE!"
I would sit around with the other bigfeet and discuss the impact of the early French impressionists on the modern art movement or debate the ramifications of some of the more cutting-edge theories in quantum physics while shamelessly scratching whatever itched at the moment.
When I got tired of the conversation, I would grunt, grab my mate, and lead her to my fresh bed of pine needles where I would complement her on her muskiness while giving her a quick flea, tick, and lice inspection. Then I would treat her to a solid 8 seconds of monkey love, only better... bigfoot passion, yeah baby! Since bigfeet never bothered to invent pillow talk, I would fall asleep almost immediately afterwards, snoring loudly to indicate my contentment.
Such would be my life as a bigfoot, and it would be good.
I never realized until this moment how much I have in common with Sasquatch.
I would be an osprey. Because I could fly, catch fish anytime I was hungry, be a snake eater without scaring away all my friends, live in a high rise tower over a fresh water lake for free (well, after I build a nest with twigs and branches), and I would be able to hover and dive bomb as well as soar and hit the afterburners. Plus I would be magnificent to behold, have beautiful piercing eyes with amazing eyesight, and get to make new babies every season with my mate for life.
And I would not have to pay taxes to the man or save money for retirement.
