I have no idea how long I’ll live. My dad lived to 86, my mom 76 and my eldest sister only 59. Mom and sister were heavy smokers and died of lung cancer and COPD/emphysema respectively. I’ve never been a smoker so their longevity isn’t a good indication of mine. I just try to live a healthy lifestyle as best I can.
I would like to live only as long as I have a good quality of life. For me this means cognitive ability, mobility, and at least some people/relationships that are important to me. I hope that by the time I reach an advanced age, there will be more individual freedom to make end of life choices. A friend who is 90 told me she’s been ready to go for a couple of years now. She is still in decent physical health with no serious chronic conditions, but she says she is in pain every day and can’t see or hear that well. Her husband and close friends are all gone. If I’m ever in that situation, or worse, sitting in a wheel chair vegging out in dementia care or a nursing home, I’d rather not continue with that life. OTOH, if I can be in good mental and physical health, be with my DH who is also in a similar condition, and we are taking a global cruise together at age 100, that would be wonderful!
