The Progress-Focused Approach: Can we keep on making progress into old age?

Is it conceivable that our entire life may be an upward trajectory until the day we die? While it is undeniably true that some functions will start to decline from a certain age some other functions may get stronger well into old age. For instance, as we age, most of us get better at emotion regulation and we tend to get a more positive and optimistic outlook on life. Also it appears that we become better at pattern recognition and at making better judgments due to our tacit knowledge (more about this). In addition to this, there is another point which seems to allow for a continued progress mindset. Even though some capacities may have become weaker this does not necessarily keep us from making further progress. We still may proceed, perhaps at a slower speed, but still.
