In that case I suspect that your time of birth could be a guesstimate. If the given time is correct you should now be having a career. Career does not mean a salaried job in private or a government. Every job you do is having a monetary value associated with it for if you did not do that job someone else will have to do it for which a payment has to be done. However what have you been doing in the last so many years? I am sure you would not have been sitting idle.
