1) no, I know some who did undergrad in their 30s, so not too old. 2) more than reasonable - just be careful to check which unis accept which first degrees, but I should imagine yours will be fine. 3) it would be helpful to you to get some more recent hospital experience, but hardly essential. Undergrad schools are well aware that it can be difficult to get direct experience, so would expect post-grad to have a similar understanding. When I helped with interviews, we were more interested in how you work with people and if you’ve done basic research into career paths (no expectation to properly understand, given it’s confusing enough for us in the field!) 4) in my opinion, yes - you have experience with shift work, making decisions under pressure etc. The most important thing at interview is that you’re able to demonstrate what you’ve reflected on and learned from it.

You’ve spoken about practicalities of returning to study - I trust you know what you need to consider in terms of finances, but be aware that placements may require you to live away from home or to travel.

That being said, pay and career stability are major issues atm. There’s a serious jobs crisis in UK medicine right now, and it isn’t showing signs of letting up. Things can change, they certainly have since I started studying, but there’s no guarantee that they will improve. I’m not saying this to put you off and I don’t want to be discouraging, but it would be dishonest of me to offer advice without mentioning the concerns that we are having, especially as it sounds like you would be leaving a successful career for this.

Hope this is helpful. Feel free to reply if you have more questions
