Not much one can do about hereditary factors, but everyone should try to stay as healthy as possible. Exercise and a healthy diet can make a difference and help to keep you off of some prescription drugs which can harm your liver and kidneys over time. We all want to live a long, healthy and happy life. Of course living to be very old will eventually land you into a nursing home. Unless you can afford the best nursing home or personal care; those last years in a nursing home aren't going to be very pleasant. My father was in a nursing home for 7 years. His insurance didn't afford him the best nursing home. My dad hated the food, and when he soiled himself, he was often left in bed or his wheelchair for hours before a nurse's aide would come in to change him. The cleanest I remember seeing him, was right after he died in the home. They cleaned him up real nice for the hearse to pick him up and take him to the funeral home. Nursing homes are careful to protect their reputation. Anyway, I don't want to ever end up in one of those places after seeing my dad in there. I was told that a group of lawyers owned it. It wasn't the worst place; just average, but they often hired after school help. My dad had 2 sets of dentures and they disappeared. I think some of those kids working after school didn't want to be bothered or found them disgusting so they threw them in the trash. Unfortunately, that is the way some or many nursing homes are, unless you can afford the very best care. Makes me afraid to get old.
