We need more Doctors and Nurses . . which leads to needing more hospital beds and ambulances.
We also need more Social Care and better infrastructure to run it efficiently.
More Dentists would be a boon, especially NHS rather than private.

edit: you may find that the 'Conservative silver vote' is a myth, us pensioners have been there, done it, and have all the T shirts. Many probably slam the door in the face of elections now
