Expanding one’s knowledge base is a surefire way to stay mentally alert and engaged. To facilitate this, some communities provide on-site lectures or continuing education classes. This can take the form of any education, from learning more about personal finance, to learning how to organize groups.
Other communities arrange for residents to take advantage of the academic and cultural offerings of nearby colleges. Today, an increasing number of colleges are offering more classes online. It can be a perfect opportunity for an enterprising resident to gain more knowledge from the comfort of their room.
Here is a link to Open Culture to access example online classes.
