Why would someone enter nursing later in life?

I can think of several reasons. 1) It's been a life long dream. 2) Their children are grown and out of the house. Now they have time to do something for their self. 3) Their financial situation has changed and they need to support themselves. 4) They or a loved one had a life altering health crisis where a nurse was invaluable support. Now they want to pass that care on to someone else in a similar situation.
I could go on for days.

I would think to enter nursing late in life may mean your current position is unfulfilling.

Nursing need’s special personalities to last in this field.
