Isn't it also 'experts' who tell us to get the flu jab every year? Funny that.

I also said "If you've never had flu before then maybe have it, otherwise the choice is yours", in other words "make ones own personal choices based on the facts available" just as you said. Your wife, as a nurse, will know from her working experience (unless she kept her eyes and ears shut all her career) that there is always more than one set of 'facts', especially amongst the 'experts'!
My mantra is exactly the same as yours - 'beware' of experts, no matter what their field of expertise.
Personal experience at the sharp end of the health service this last year has only highlighted the fact that many 'experts' in their field can often be highly overrated and not so 'expert' after all.
I have always made my own personal choices based on the facts available. Sometimes, however, it can be very hard to get hold of the necessary 'facts', even when it should be anything but! As a result I am now particularly wary and suspicious of mainstream medicine which is overly drugs led, imho. But, just in case you come back at me on that last one, I am most definitely
not some sort of 'alternative therapy' freak! I base all my decisions on hard facts, evidence and personal experience.
Think you will also find if you re-read my original post that I didn't actually say that my two medics were 'right' or 'wrong', merely that they have never had flu jabs. I didn't qualify why ☺
