An Old Dave Learns New Tricks

I've learned three new things recently:

1) my wife taught me about this weekly workout schedule, and I've adopted it and it seems to be working-- my knee doesn't hurt, and I'm always sore, so those are good signs;

2)  I listened to a podcast about the power of NEAT-- NEAT stands for non-exercise activity thermogenesis and basically encompasses all the random walking, standing, fidgeting, and daily movement you do and apparently this makes a HUGE difference in how many calories you burn during the day-- plus, if you take a fifteen minute stroll after you eat a meal, you really lower your glucose and blood sugar levels-- so I've implemented both these strategies and I've actually lost a few pounds (without going on Ozempic, which is what it seems like everyone is doing-- but I really like my big round butt, so I'm not messing with that shit) 

3) AND I learned something else today, and I came up with this out of the blue in the middle of teaching-- so here's the scenario: sometimes I have the projector on but I want kids to write stuff on the whiteboard so instead of having whatever Canvas announcements I have projected, I just want whiteness-- I don't want to shut off the projector because it takes a while to turn it back on-- so I search up a white background on Google and I project that version of whiteness and then the kids can write on the whiteboard and their writing is not obscured by the projection-- because it's white-- but today I had an epiphany, and instead of searching up a white picture, which is always weird and has borders, instead of doing that, I chose a little bit of white space that was already on the screen and I used my fingers on my touchscreen and I just kept expanding that white space until the projector was just projecting all this expanded whiteness onto the board-- and then I made the students tell me I was brilliant . . . but the real question is: will I remember to do this the next time I want to project whiteness?
