yes, Knowledge is a two way street. We can learn from each other. Age bias is bad both ways. The saying "Its hard to teach old dogs new ticks" is WRONG and this articular stinks of it.
Unfortunately, it's a saying that is rooted in truth; as you grow older, your neural plasticity and fluid intelligence steadily declines, and so learning new tricks is, perhaps not impossible, but certainly more difficult - so it's important to recognize this and make the extra effort to remain open to new ideas and new experiences, the way one does almost unconsciously in youth.
