There are so many factors which weren't considered. A few examples (not in any particular order): 1. What's the life expectancy of Jews and Arabs of similar socio-economic backgrounds? (I bet little or no difference) 2. What is the trend of life expectancy for Arabs over the past 10-20 years? (I bet it is steadily improving) 3. How does the relatively poor driving record of Arab drivers skew the results? 4. How do honor killings/feuds skew the results? 5. How does the typical Arab diet skew the results? (Hard to say which culture's diet is healthier. Also, health standards in each sector varies - probably better for Jews) 6. How does the type of jobs taken by Jews and Arabs affect life expectancy (Arab construction workers are probably exposed to much dust, toxins, sun [skin cancer], etc.) The bottom line is that a 4-year difference in life expectancies doesn't have to be political, e.g. does anyone say greater longevity in women is due to discrimination against men?
