Yes, it does bear repeating that there are a lot of options within the overall healthcare field for an academically strong, scientific minded, driven and ambitious young person that will be both (a) more lucrative (b) less physically, emotionally, life-consuming-ly intensive than medicine that as a bonus don't also involve moving to the other side of the world (unless they want to of course!). I don't just mean nursing, allied health professions, healthcare scientists and so on (although it's a pity these are so often viewed as '2nd choices' for those without quite the exam results to be medics) but also research and clinical trials roles, pharmacology/medicines development, bioscience, medical engineering, digital medical technology, there loads of ways in which you have a really interesting and very rewarding (both financially but also in terms of making a difference) career choices if the whole lifestyle choice (and medicine really is that, wherever in the world you do it IMO), dedicating every waking moment to it, 24/7 working kind of thing isn't for you/your DC - and to emphasise I don't blame you/them for thinking this, at all, but it would be better all round to explore other options rather than training in medicine and ultimately not practicing where you trained.
I don't want to be critical of schools careers officers who do a difficult job (technology and the jobs that go with it are rapidly changing) and medicine is of course a brilliant career for those suited to it, but I really feel a lot of bright young people aren't well advised about this kind of thing and a lot of kids with A grade science A-levels are pushed towards medicine almost as if the's 'number 1 prize' ultimate ambition, without them being aware of the whole wide world of other choices they can make that would achieve a lot of the same things as medicine (money, prestige, helping people, hands-on non desk job work) without a lot of the drawbacks!
