In accordance with some of what Pi Day represents, I thought I’d make a point to those that refrain from intelligently responding to posts and have little interest in thoughtful writing.
Studies suggest that cognitively stimulating activities, such as typing intelligent, witty and humorous writing (especially involving wordplay) can build cognitive reserve. This reserve helps the brain compensate for age-related decline and can help resist the effects of neurological conditions like Alzheimer's. Of course, much needed research is still ongoing and required, but a body of knowledge is slowly emerging. Use it or lose it.
It's been stated in different ways over the years on this forum that by and large, most of us here are no long “spring chickens”, to put it delicately.
I have a doctor friend and the other day he and I were discussing this subject. He made 2 points worth sharing.
First, he said that when someone is diagnosed with age-related dementia that the condition didn’t just appear that day or even that year. The decline most likely began 10 or more years ago. He also said that clever, intelligent speaking and writing should be a part of one’s “daily portfolio for cognitive resilience”.
To craft witty and clever writing demands mental dexterity, it involves playing with language, drawing on memory, imagining scenarios, and thinking outside the box; even upside down. These activities can help keep the brain active, improve focus, and build resistance against mental incapacity.
I notice, for example, that as of this writing, 36 people have viewed this very post, yet only 3 have responded (all with clever and wit). To the other 33 that didn’t/couldn’t reply, I say this: if simply viewing is your typical approach, then you are missing out on valuable opportunities to “clear out some plaque”; you’re “leaving money on the table”.
I realize that time zones may also explain some of the 33. Afterall, for our friends in Europe, it's Tuesday next week and in Australia, heck, it's some time back in February!

OK, I’m done (for now) with “Dr. Steve’s method for achieving mental sharpness well into your 90’s”.
What I really wanted to say is Pi Day is proof that math lovers can also have their irrational days . . .
