Which risk factors cause the highest number of death?

The given horizontal bar chart presents the result of the survey conducted among all age groups and both sexes. It aimed at finding out which of the following risk factors cause the highest number of death.

And it does not come as a surprise to me, because due to declining fertility rates and rising life expectancy there are more elderly people than youth.
