If you were told it looked like you only had a couple years to live..........
I would tell my family and especially have a sit down and try as best to explain to my 13 year old daughter about what is happening. She would be DEVESTATED if this were to happen. I would make sure that my church family knows also so they can be there for my wife and children and grandchildren. I would sell anything I would not need after I was gone to try to give my wife more capital to go on with. I would request to be creamated to save money on burial expenses. I would just try as hard as I can to make it as easy on my wife and children and grandkids so they can go on. And let them know not to weep for me when I die, but to celebrate the life I have been blessed to live with them. Having died on the operating table 3X in 2004, I am blessed to be able to wake up every day and enjoy another day. God is good.
