In human geo yesterday we took a test that was kinda hard but easy too. I didn't know we had to blog so im doing it today. We also learned that woman live longer then men. Also in some countries there is a huge population of children 0-4. In other countries there is more 30-35 years olds then there is 0-4 year olds or 5-10 year olds. Depends on the country the pyramid is different for all different countries.
