Life Expectancy

Hi all,

I am currently doing a reading for someone who is very ill. She's running a dasha that looks promising based on the position of the dasha lord in the Rasi and especially for career due to dignity in the d10. However, she'll soon be running an antardasha that I believe could be associated with a maraka. I'm worried she won't make it past next January. I don't want to make predictions past that point if she were to pass away before that. I was wondering if anyone who's learned the life expectancy techniques would be willing to help me determine "how much time she has left".
