Mathematical logic applies to so much.

Studying mathematical logic gives you a perspective into how subjective and ill defined most topics of everyday conversation are.

Mathematics gave me an enjoyable career.
I taught for nearly 40 years and loved 99.9% of it.

I was very fortunate. .I found a calling that I enjoyed
and got paid for it. .No physical labor, met thousands
of fascinating people, and hopefully improved their lives.


I have a few T-shirts with my favorite sayings:

. . . . . \boxed{\begin{array}{c}\text{Do what you love.} \\ \text{Love what you do.} \end{array}}


. . . . . \boxed{\begin{array}{c}\text{I touch the future.} \\ \text{I teach.}\end{array}}


. . \boxed{\begin{array}{c}\text{Three reasons why I teach:} \\ \text{June, July, and August}\end{array}}



My friends and neighbors would ask,
. . . . . . . . "Do you really take the whole summer off?"

My reply: "Yes, but I left a wake-up call for Labor Day.
. . . . . . . . I want to get up at the crack of September."

Alfred North Whitehead and Bertrand Russell wrote a book about logic titled Principia Mathematica. I remember it took many pages to prove that 1 + 1 = 2. I don't see where mathematical logic of that order would have any practical use in everyday life.

Use is far too loose a word to use like that. Something being enjoyable is a reasonable "use" from my perspective. And from that point-of-view, all mathematics is useful in daily life to those who enjoy their practices.

In any case, I do not think the poster of that comment meant anything nearly so onerous as that proof when he said "mathematical logic". Another reason why these kinds of discussions are tiresome and often pointless, because everyone is far too avant-garde with how they treat what they're saying and the participants in such a discussion are either unable to see they often don't disagree or become so mired in clarification that all the fun goes out of it.
