No astrologer will tell anybody regarding longevity, except some in their you tube channels. When somebody told you, you have courage to bear this, should have asked the question then and there. I advise you do not be mislead by youtube channels.
Your lagna fell in Scorpio at 22°46’21” which is co-ruled by Mars-Mercury-Moon. Longevity is decided by Moon. Moon is in 5th house and signifying his star lord Venus (lord of 7th, 11th and 12th) 2nd house (a maraka house) and sub of Jupiter. Jupiter significations are 4th and 6th (detriment to maraka, roga stana). So you have longevity.
Running period is of Jupiter dasa-Venus bhukti. Jupiter is signifying his star lord Mars (lord of 6th in 4th) and his sub lord Mercury who is signifying 3rd house (House of longevity).
Bhukti lord Venus is signifying his star lord Mars (lord of 6th in 4th) and sub lord Rahu (in 6th house-roga stana), who is signifying Sun in 4th house (house of comfort). Then it is not indicating death.
For death, we see the death inflicting houses along with badha stana significators. For happy events like marriage we see the same houses. So nothing to worry. Again we have to link the transit.
Don’t trust them who told you that you would die within 2030. At that time your age would be 64y. Next bhukti is of Saturn who rules for 19 years. In Saturn bhukti, which ends on 17-4-2050, you will have your last journey. In 2042-43 you should be cautious in health aspect.
Good Luck
