At the same time, there are many others who, for whatever reason, cannot play sports or do the same kinds of activity even if they wanted to do so. They may have health problems, injuries, or other limitations. They may be equally motivated and live a normal life despite these limitations. They also just may not enjoy physical exercise or exertion and prefer a more sedate life. Some may be disabled and have been for some time so they’ve chosen a different path for themselves, one that allows them to do the things they enjoy without physical restraints.
So when we are speaking with our aging parents one of the key factors to consider is the degree to which they want to and can be active. Then you can help them reach that level. Come to think of it, when we're thinking ourselves about how we plan to live the rest of our lives, this might be a pretty good way to view it.
