You will have bat-like wings attached to you. Your body structure will be different so you can fly. The wings will be attached to your shoulder blades. Your bone structure will be hollow so you'll be light. If in high places, you'll use the wind current to glide, but in low places it'll be difficult to lift off the ground. Plus you might get exhausted from flapping your wings alot & if you're carrying something, thats more weight on you.
