First time I ever met him. He looked about 14.

Young doctors are far better than older more experienced doctors for two reasons.
1. They are still enthusiastic about the job and not jaded old buggers who believe they have seen it all. Doctors have a very high suicide rate.
2. They are up to speed with modern techniques and treatments. Most older doctors are way behind in this respect. I'm sure some of them believe that using 'leeches' is the latest thing.
A couple of years ago my diabetic nurse changed my prescription.....after a few days I realised the new tab wasn't working, my blood sugar had shot up....so I phoned for an appointment with nursey to be told she had gone on holiday!
Great! So I was booked in to see a doctor....appointment time and I saw a newly qualified dr ..... didn't inspire confidence when she spent 9 mins of the 10 mins I was in, looking up in medical books, what the tablets I was on, did and when I suggested I go back to taking the old tablets, again she had to look up what they did also.......She agreed I should go back to the old tabs and book an appointment as soon as nursey came back of hols....
Wish I hadn't had bothered to go and see the doc, tbh and just reverted back to the old tabs.......
