Thanks for all the replies.One thing many dont understand is that medicine is a very demanding career (especially hospital medicine)-it is very difficult to do anything else outside a medical career, you cant always plan your life because you can be posted anywhere to work-you do nights, days, long days-its tiring. To a certain extent, there are some areas of overlap when it comes to finance. Im not claiming that a career in finance is going to be rosy. Medicine is a very rewarding career-no doubt, but it isn't where my passion lies. Im just nearing the end of my foundation training-first two years post grad and this is the stage where you make a decision to stay or leave. I have given myself plenty of time to think very well about it in order nott o make the wrong decision. The point is, I just dont feel complete and sane without matematics. I really love maths, I just cant live without making it a part of my everyday life. I really dont mind starting uni all over again-in 3yrs time, it'll be done.Once again, many thanks to those who have been helpful.
