  • Thanks to the RUclips algorithm, I discovered Mr. Feng, a 94-year-old calculus teacher, ‪@ycmathematicsphysicsandche5659‬ . He said in his note that teaching makes him happy and makes his life meaningful, which I resonate with so much. I want to make a video to introduce him to you! Please consider subscribing to his channel and supporting what he does. Thank you.

    someone once said, there are two types of teachers. teachers by chance, and teachers by choice.

    It may sound a bit obvious but as you get older, especially after the age of ‘retirement’ it’s important to understand that having a purpose and goal in life very much plays a role in a person’s longevity.
    I’ve seen people who retired and thought they would live a life of leisure, only to find themselves miserable and mentally declining because they stopped having a purpose and goal in life, and no golfing everyday isn’t a ‘purposeful’ lifestyle, unless you’re a pro-golfer.
    The fact that Feng hasn’t lost his motivation and desire to teach after all these years says a lot about why he reached 94 and with the energy he has.
    There is another 93 year old who displays a similar energy, actor William Shatner…

    YOU BECAME MY IDOL, as everyday you inspired me to solve tough questions and work hard.

    This literally made me cry. I know you're being humble, both of you, but you clearly know so much more than just math or physics. You are deeply and intimately familiar with what it means to connect with other humans, to understand how they understand and to translate incredibly complicated concepts about real or theoretical worlds and to bring together the experiences of your students with your own. I used to wonder what I should do with my life when I was still in high school, tried to figure out how or where I would do the most good, but in time it became clear that the most important thing you can possibly do is whatever you love doing, because your love will radiate out and attract and inspire others to do the same, and then you will all have a more sublime life for it. So thank you, for teaching, for shouting out a fellow teacher and sharing your popularity with someone who might not have as much time as the rest of us, and for caring about people and about yourself.
