The major issue is that people as a rule are lazy so expect a simple quick fix to all their problems in life.
Illness, pop a pill
Fat, gastric band
As a previous poster mentioned most problems that a GP comes across will be fought and fixed by your body with a little assistance of paracetamol or ibuprofen to keep down temps.
We have become too reliant on an easy fix and need to return to eating properly, exercising and not being too clean.....
Build up your natural ability to fight illness, only go to a GP when you have a serious problem. The NHS generates this lazy reliance on the GP for everything!!
