Cheers, to prove your point one of the two permanent Doctors at my surgery is retiring this year, I'm guessing he's mid 50's. He has "other" medical income including being the Doctor in an ambulance that follows the racehorses around Haydock Park. The quacks is in a deprived area, they struggle to get Locum Doctors. I fear it will get worse and there's people at that surgery that really do need a lot of help.
Same in my practice in Altrincham. I was called by the receptionist after a blood test to say my doctor needed to make a telephonic appointment to talk to me about it. When I said my doctor's name she told me he had left the practice over a year ago! Nobody had informed me or told me which doctor was now assigned to me which I found incredible.
He was probably in his mid fifties and had retired early and was doing some locum work. A lot seem to do little earners on the side once they retire. I used to have to have an ENG1 medical every two years when I worked on the ships. The doctor who did it was retired and did them from his house in Disley. This medical certificate incorporated airline staff, rig workers etcetera so I guess it was a nice little earner. He was very thorough and after one medical he was very impressed with my fitness for my age and told me I had reached the level for a jumbo jet pilot and their criteria was very stringent. I told him I was very happy to hear that, there was one small problem though I couldn't fly a bloody jumbo jet lol.
