What if Assignment

How would your life be different if you did not have bones in your feet and hands?

I think that life would be very hard if you did not have bones in your hands. How would we be able to open a door, wash our hair or even drive a car .We would not have all of these inventions that helps us in everyday life. People might find a way around it over time so they can come up with a way for you to shake someone hand or you can pick up things more easily.



How would your life be different if you had your skeleton on the outside?

The whole history of the world would have been completely different if our skeleton was on the outside. That would mean that there would no longer be black, white, or Asian people. Everyone would be the color of their bones and in would be very hard to tell people apart. Our organs would be dripping on the ground and they are not protected enough. You could fall on the ground and your stomach could bust then you would be dead.








How would your life be different if your muscles did not connect to your bones?





If our muscles did not connect to our bones I would not be sitting here now. No one could get to where they need to go. Everybody would be like this live doll that can not do anything but blink.We would not be able to eat food cause you dont have any muscles on your jaw to chew. People cant survive anywhere if your muscles are not connected to your bones..

How would your life be different if your spine was one long bone as opposed to multiple bones?

If our spine was just one bone we would have to remodle everything. Cars would have to be taller certain sports would not exist.We also would not be able to bend our neck without feeling pain.It would be really easy for someone to brake their back by bending the worng way.I think that it would be ten times harder in life then is now if we only had a single backbone.

Cosmetic surgery is the worse thing you can do to your face. They have to cut up your face and other parts to change it. Sometimes people dont heal as well as they where told by the doctor. You could get sick from the fake parts that where put in your skin.I would never do that to myself.

No. Make up can only help you to a certain point. It can cover up maybe a small bump or something. It cant help you when you have a big scar on your face or its deformed because of some type of surgery. I think they have low self estem so they tell people that.

Yes. Some cultures veiw cosmetic surgery as an insalt. They have there religous reasons for not changing the way they look. People all over the world have different views on it but i still say they crazy for doing it.
