+Processing Life Expectancy Tables
+=================================
+
+The Office for National Statistics (ONS) produces [life expectancy at birth
+tables](https://www.ons.gov.uk/peoplepopulationandcommunity/birthsdeathsandmarriages/lifeexpectancies)
+for various geographies for England and Wales. However, because they are
+statisticians they produce nasty broken Excel sheets instead of nice simple (and
+easy to use) CSV files. 
+
+In this exercise we will be taking a pair of raw data files
+(`counties-m-birth.csv` and `counties-f-birth.csv`) that have been saved out
+from Excel as CSV. They contain male and female life expectancies at birth for
+English counties. You will need to edit the file `life_expectancy.py` and add in
+some code to extract the lines we want (a header row and the ones with figures on), 
+and then output them for each file. 
+
+If you finish that task then you can think on how you might add the ability to
+sort the rows based on a column the user specifies, or how you could combine the
+male and female figures to allow them to be compared more easily.
