Why can't I fly like a bird?

Answer 1

Bird anatomy is better suited than human anatomy for flying due to a number of reasons;
1.Bones are a significant amount of your body mass, yet bird bones are more porous or hollow to make them lighter.
2.Birds have huge chest and shoulder muscles in comparison to humans, thus they can pull their wings with much more strength than could a similar sized human.
3.They have wings and feathers to increase the surface area that comes in contact with the air.

Beyond biology, simple physics says that there are limits to how big something can be in relation to its size. Basically, strength is proportional to the cross sectional area of muscles. Thus, if you are 10 times the size of a bird, your muscles will be 10 times the width and 10 times the depth meaning you will have (roughly) 100 times the muscle strength of a bird. Sounds great so far. However, your body mass will be 10 times the width, depth, and height of the bird. In other words, you will weigh 10x10x10=1000 times as much as the bird. So, now you have 100 times the bird strength but 1000 times the bird weight to lift. If the bird was just barely lifting itself, you would be stuck with 10 times the effort due to strength to mass calculations mentioned above.

All said, you could always try hang gliding.

Answer 2

Your wingspan, and more importantly, the shape and surface area of your wings (arms) is insufficient to generate enough lift to get your heavy butt off the ground. The best you can do is glide like a bird, check it out:

Answer 3

It would also take more muscle power than humans have to flap the wing span which would be necessary to lift our weight.

Answer 4

Not enough self esteem. Listen to Dr. Phil and get your act together BOY!

Answer 5

Not aerodynamically designed for flight.
Too heavy, no wings, no strength to energize lift, etc

Answer 6

you should try to fly from a high building

Answer 7

you have no way to create a bouyant force equal to or greater than the downward force of gravity acting upon you.

Answer 8

2 heavy...no wings

Answer 9

You just haven't found the right drug yet!!

Answer 10

Cause you ar a human you wally!!!!!!!!!!!
