I just searched for a thread on this as I know there have been some before, and indeed that I myself have even commented and voted to say that the poster is being VVVV U. It does seem mad to embark on a course that won't finish until you are practically 50 and then even given we are all going to work til our 70s, that's only 20 years, i.e. a half career.
However.... due to personal circumstances, I am living overseas in a country in which it is possible to study medicine more cheaply that the UK, and it's still very well regarded. We will be here for at least the 6 years required to study (timeline isn't a problem). I could probably get the foundation years in too, or at least a couple of them.
I don't enjoy the job I trained to do. I'm currently doing it from home but I won't progress this way. I don't think it will be particularly easy to achieve the level I was at after we move back to UK (current plan). And anyway, I don't enjoy it.
I'm not under financial pressure, I would like to have a career I can be proud of though. DH would prefer me to work but there's no particular need to make more money. I haven't discussed this with him yet.
I did science A-levels and got good grades (a zillion years ago, I remember nothing). There is a single test to do to apply called an IMAT, I assume I'd have to study.
Thoughts? Until this idea popped into my head I would have thought this was mad, but it kind of seems like I've been given the runway to do it without the usual issues that people cite.
