Quantity of life vs. Quality of life

Which one matters more to you? Would you rather live long or live strong? If you could be guaranteed to live until a certain age what would you do right now until that point? Are you living your life to the fullest or do you play it safe most of the time? Would you rather die on your feet or live on your knees? Does that even make sense to you? Do people in family live long lives or do they check out fairly early? When it's all said and done, are you happy with what life has given you or do you feel cheated?
