Thank you for the opportunity to help you with your question!
I think there is no right or wrong answers. I would rather live a shorter life with a higher quality of life than live a long life with infirmatives. A long life without quality is just a waste of time. You really couldn't enjoy your life at all. I would say that having a long lifespan without a quality is a suffering - you are not going to be happy. On the other hand, a high quality of life makes a person happy. It is indeed short, but you would enjoy every moment when you are on earth.
Please let me know if you need any clarification. I'm always happy to answer your questions.
