If you are about to go, go like my dad 1.5 years ago. He was 90. He had leukemia. He told mom the night before, "I just feel so exhausted." He used a walker about 5-weeks.
Later that night, she caught him doing squats, bracing himself with his walker. Dad was going to work himself back into condition. Next morning she gets up at her usual 4:30 a.m., she let him sleep in. At 7:30 a.m. she went to awaken him, "Sweetheart, Sweetheart." He didn't respond; dad died in his sleep. Dying in his sleep, was the only comforting thing.
I live 1,500 miles away. My tenant above my law office died unexpectedly in his bed. The police officer who did the welfare check told me my tenant died with his eyes open. I asked my brother who was present. My dad died with his eyes closed, which was comforting, to me.
