The astrologer is frightening you unnecessarily. Give him some few bucks and he will change it into something better. You are currently running Rahu Dasa and your Maraka Dasa will come into effect only in 2045 and by the time you will be in the Astral World where we will possibly meet and have a discussion. Be cheerful and enjoy life as is given to you. You will live up to a nonagenarian.
