Life has taught me a lot, I have been caregiver to many. Big tough men that never thought they would be taken to their knees by illness. To depend on the love and concern of others to get them through the tough times, not only physically but also mentally. You can say you have prepared is one thing but when the crap hits the fan you will need other kind humans to care for you in all ways.
No, I do not know you as a person but I know that all humans will come to a time in their lives they need tender loving care. Yes, I would consider a person's behavior before I stepped in to help. Why would anyone want to try to help someone that is abusive, angry and mean. I chose to take care of husband's and my best friend after he had a leg amputation. They were going to send him to a rehab place that would not give him the care he needed.
It was not easy, taking care of the area of surgery. It was not easy giving him a bath, I only did the body, he took care of the private areas. I washed his hair, gave him haircuts, trimmed his nails. I emptied urinals and took care of the bedside commode for the other. I cleaned his false teeth, cooked his diabetic meals and snacks. I did all his laundry and took care of him having a clean comfortable bed.
I gave my life to taking care of my husband when cancer struck. He was ill for 5 years until he passed. I also brought my mother into my home when she could no longer live alone.
You are so hard headed that you can't see your nose because of these stupid notions that you won't ever need help. Far be it from me to judge the perceptions you have formed. If you are lucky you will never suffer an illness or disability that would require help. May God bless you and call you home with a quick death without suffering. I pray for the same thing every day because I have seen the long hard way too many times.
