We already have all the consultants we need
The only consultants we need you can think of as a kind of doctor.
We have ENT consultants (no not walking trees) who deal with ears, noses ant throats.
We have consultant surgeons. They are called Mr, Mrs, Miss and so on because we were taught to be very polite to people with knives!
We have all sorts of other consultants. They will do things like save your life, help you get better or even stop you getting sick in the first place.
The consultants described in this article are not the same thing and need a different name - whether we really "need" them or not.
