Life is exciting when you decide it, the same way you are happy when you decide it: it is up to you.
You want to fight? There are all kinds of professions where you fight for the people. International health is one: the right of everybody to have access to care. You can tackle it as a doctor, as a lawyer, as a politician, an army dentist as on the picture, or as a cartographer or a statistician. You can even do it as an educator, because adolescents who take responsibility for their health are more effective in staying in good health.
