You are already 58 years old and you mean to say that you never had a job in your life. Then how were you able to get your daily intake of food. I am sure not by begging!
A job in astrology only means a career to earn your living without which you would not have survived so far. We are all living in Karmakanda and each one of us have to do some work or other. We cannot sleep away all the 24 hours of the day even if you want to.
You possibly have mistaken a job as one where you are being employed under someone who gives you a salary. Doing your own job like Agriculture, business of your own etc. are also indicative of a career. Why begging also is a career for many some are organised begging and some begging for alms to survive on a day to day basis.
