My friend is very fond of studies. Her father couldn't fund her further studies after her bachelors, so she joined jobs. She left her job at the age of 40 and completed her master's degree in computer science. After that she got a job again. Now she is saying that she is not learning much in her job and it is monotonous, she wants to leave her job again and pursue Ph. D. in data science.
I am clueless if I should discourage her or encourage. She will be 50 by the time she completes her PhD. Are there many teaching job opportunities at that age, given that she has been in industry throughout and not into teaching? She says she wants to keep engaged in studies related activities throughout life and doesn't want to retire till death.
Can you please suggest what should be the best thing for her to do?
