beauty video

Do you think that the symmetry test conducted on the baby was flawed? How? Describe how you would design an experiment that could fool the baby and skew the results.
I think that it was flawed because it could be looking at some longer because they looked worse. It might remind them of someone they know.
What is missing from this video about beauty?
They are missing qualities like personality. Also personal preference is said to be none important. Which isn’t true. A lot of times someone says they think a person is really beautiful but I don’t think they are.
What are features that might break the "typical" beauty rules? How are these different from the "typical" beauty rules? To be beautiful doesn’t mean being totally simectical. Somebody having none
simectical hair doesn’t mean its not good looking. Also you don’t have to have vivid colors for beauty.
How does this video make you feel about beauty? That people take it too seriously. They become crazy about it. I thinks mostly deals with personal views not a science that they were making it.
What is it about the skin that makes it return to its place? What property is this?
What are the risks of cosmetic surgery? Would you ever do it? What would you be willing to risk for cosmetic surgery? How long will it last? I think its stupid. People act crazy about how they look. I don’t want anything changed of myself. I’m happy to be how I am. So I wouldn’t be willing to risk anything for it.
Someone in the video is quoted as saying that "make-up can make anyone prettier." Do you agree with this? Support your answer. No I don’t think so because having make up on isn’t what you really look like. It is a mask that they are hiding behind because they are worried about how they look. It is cheating your looks like plastic surgery.
Do you think that there are cultural differences in how cosmetic surgery is viewed?
Yes because different cultures have different views on physical beauty. As well as they might have different views on how you can change your body. Like some would say god made you how he wanted you and to change that is an insult to god.
