Just goes to show you weren't paying attention at all.
The data is for SUICIDE...self inflicted intentional death...not letting oneself go and dying young due to ill health.
Sorry I swear I didn't see the title only the x and y axis. That's what made it so confusing.
The difference in suicide rates between men and women could be how they handle pressure and stress. Maybe women gravitate to other self destructive behaviour rather than suicide.
We have to assume that men and women deal with stress in the same way for us to be able to compare suicide rates between genders.
