- Being taught
And since keeping our minds active increases not only our enjoyment of life but our mental health as we age, it makes sense to do everything we can to (1) heighten our powers of observation (bird watching, anyone?); (2) seek out role models to imitate; (3) experiment in the boardroom, bedroom, kitchen, garden, etc.; (4) read widely; (5) and take classes in anything and everything that tickles our fancy.
Speaking of keeping our minds young and enjoying life, I loved this profile of Carmen Herrara (photo above), which appeared on the front page of yesterday's New York Times: "At 94, She's the Hot New Thing in Painting, and Enjoying It". If you've got a sec, it's worth a read.
