Quantity of life is important if you can maintain quality.
No quality of life stinks as I have witnessed with several family members who lived into their ninties with very little quality.
My mom used to say, the 70's were great, the 80's were good, the 90's stink.
Hopefully I get to the nineties and see for myself firsthand.
