With astrology, you can know what your life span will be. However, astrologers don't reveal a person's lifespan as per the birth chart until it's required. We can still hint at whether the person will fall into the Deergha Ayu category, the Madhyam Ayu category, or the Laghu Ayu category. We can assess how long a person will live depending on the astrological indications in the birth chart. https://www.vinaybajrangi.com/health-astrology/life-span/what-will-be-my-life-span.php
