Calculating longevity

Hello
I would like to know my longevity as I have to make some important decisions. One of friend a novice in astrology said in another 12 years I have health related hurdles. My details are:
Date of birth:19 January 1981
Time of birth: 4:30 am
Place of birth: Paris, France

Can you please calculate my longevity?
Thank you in advance

It is considered unethical to tell some body his longevity. Further, it is the most difficult thing to determine. If one tells it to somebody and later it is found that it was incorrect, the kind of mental turmoil the person will go through in the intervening years can easily be imagined. Therefore end of life is told only in very exceptional situations.
