Arjuna, do what you gotta do, family is much more important than this little game we are playing here... but, does your dad hunt? Sounds crazy but some say that laughter, fun, and living life are the best medicine, if he's not stuck in a bed try to get him out.

Sorry if that was a crazy suggestion (really sorry if it offended), but I know that my farming grandmother fought off everything the world could throw at her long past her time as long as she could walk the field to her sisters and back every day, it was being in the old folks home that ended her battle.
