Teaching Jews is the Best Remedy

Blogger Al Fin gives us the present of free brain exercises, some of them even will improve IQ and memory. My mother used to work all the time on those things. I suscribed her to Hungarian journals of brain teasers and bought her a Hungarian encyclopedia of crosswords. Her mental acuity was perfect and she managed her bank accounts better than I do. She never did any physical exercise or sport, yet was in good health till her death (except her last two months of advanced liver cancer).

The pic shows an Old Jew, by Rembrandt. What with Rembrandt? He painted too many old Jews. He was greedy and expensive, he had many old and rich Jewish clients. Anyway, should I spend time on brainteasers and crosswords? Maybe. But they are so utterly boring and pointless. The work I am doing requires much thinking, and hope that I will never become mentally flaccid. My most extreme mental effort is in teaching. The math-addicted civil engineering students of Ariel force me to more than human efforts to be coherent. They demand the complicated equations they love, and demand from me to explain in extreme depth those little greek letter - till I reach Newton's Laws and cannot go further. They pressure me mercilessly, they make scenes in class if something is not fully understood by them, they refuse to let me continue, they phone the Decan and send letters. My brain is excercised by teaching in Ariel. I feel mentally younger and focused after a day in Ariel. And utterly exhausted.
