If a person truly believed she could fly and jumped off 40 story building?

even with airplanes and balloons, humans still cant fly, only ride in things that do, a parachute doesnt mean you can fly, cars dont mean you can move a 100 mph, guns dont mean you are deadly, a calculator doesnt mean you are a math genius, standing on earth doesnt mean you can fly through space, and lots of beer doesnt mean you are 10 feet tall and bulletproof.
