Was a bit younger at 22, I gave up being a mechanical engineer and trained as a psychiatric nurse.
pay not too bad when qualified and pretty decent if you get a couple of promotions
with the qualification you can basically work anywhere in world have mates who went to Australia, Bermuda and middle east.
No two days the same, I work in forensics - basically people who offend due to the mental illness which can be rather challenging
3 years at uni to qualify and you get paid (not a lot) to do the course
