Saving lives is a noble job

When I was browsing a social networking site,I saw some of my high school classmates.I'm happy for them because most of them are professionals.Many of them are in the medical field mostly doctors and nurses.Some are in Philippines and some are now in USA.When I browsed their profiles,I saw their photos when they were in operating room,doing some check ups and attending some patients.I am sure they always use the medical equipments such as spirometers,dopplers,defibrillators,vital sign monitors and some other eqipments in their everyday duties to save the lives of the people.I really salute them for choosing a noble job.
