You must be enthusiastic about people using ERs when they have strep throat, right?
Let me think for a few seconds about ideas. Fitter EMTs who can assist people in more demanding physical situations. A subset of firefighters who can provide medical assistance but don't need the complete fire training curriculum and so can be paid less. Maintaining the ratio of firefighters and stations which was previously found satisfactory but adjusting it for requiring fewer of them since we have fewer fires.
Your turn.
