Firstly, it's wonderful to learn you come from a country where the elderly are respected, cared for and loved for what they have contributed in their lifetime. Sadly, America can't claim the same mindset.
Secondly, like you, I never want to be a burden to my loved ones. When I can't reasonably do for myself, I'd rather be dead.
Thirdly, we can't live forever. That's the contract we sign from birth. I don't believe in hanging onto to a loved one who is more dead than alive. To me it doens't make sense. It's no quality of life for them and it's torture seeing them suffer.
Thank you for sharing your insights. Enlightening.
