One of the primary responsibilities of every fire department is to understand and best serve the community that supports it. This mission is one of the primary reasons for promoting diversity among department members — to better represent and understand the needs of those served.
But there is one demographic that, with rare exception, will never be included among active firefighters, despite a disproportionate involvement with emergency services agencies. Those are the people in your community who are considered elderly or very old.
On my department, we ran frequent calls involving older people — medical incidents, accidents, service calls, fires.
