[02:02.15]For example, statistics indicate that in the United States

[02:15.76]In other words, two out of every ten deaths are due to some kind of cancer
[02:24.11]Therefore, the risk of death from cancer is quite high
[02:30.77]However, statistics also show
[02:36.89]that 80 percent of all cancers are related to things over whichyou have some control
[02:45.24]In other words, you can make choices that will reduce your risk of developing cancel

[04:48.54]Decide whether the following words or phrases are mentioned in the conversation
[04:55.96]as factors which might influence one's life span6
[05:02.69]Put a tick beside the word or phrase if it is mentioned
[05:08.48]Then decide which two are the highest risk factors.
[05:15.97]H: Oh! It's unbelievable!
[05:20.80]W: What's the matter?
[05:24.36]H: This article says that life spans7 vary according to race
[05:31.38]income level and whether you are male or female
[05:37.18]Er now, can you guess which is the most important factor?
[05:43.84]W: Mm, I think it might be your sex.
[05:49.49]H: That's right
[05:52.66]You see, my grandma lived four years longer than my grandpa
[05:59.50]Generally speaking, women live longer than me
[06:05.33]In 1993, the average life span of women was 6.9 years longer
[06:14.36]than that of men in the United States.
[06:19.40]W: 6.9 years? I can't believe it Then how about race?
[06:27.54]H: Race... The paper says white women live 5.1 years longer than black women.
[06:39.71]W: So this means I am doubly luckly since I am a white woman.
[06:45.76]H; Yes. But actually the largest risk you could run--after being born male--
[06:53.89]is being poor
[06:57.67]Being poor is far more likely to kill you than smoking
[07:03.32]drinking, a hereditary disease, or an unhealthy lifestyle
