FIL decided when he was 45 that he was finished with his job (it wasn't a great job, the hours were quite long but the pay was average). So he decided that he wanted to become a nurse and retrained. He recently graduated (aged 51 and now has no job to go into!)
I feel he chose nursing as the NHS pays course fees and he was given grants and therefore basically didn't work for a few years (had to do some volunteering/low paid work in the hospital as he had zilch experience - hence why it took so long!).
AIBU to think that there comes a time when you've got to accept that you missed the point in your life where education was availabe and if you want to change your life for the better - working hard is the way to do it, not starting something new all together? Especially at the expense of the NHS or government supporting you, since it is much more economically viable for that training to go to a young student who will in return give a much longer service to the NHS?
