39. Class struggle and racism in America from its founding up to the present through a series of books a history post-doc friend assembled for me. “Going deep” on a topic as Tyler Cowen suggests.

I’d suggest you to take a look at what other “right” leaning people have to say about the subject. Especially Dinesh D Souza, Jordan Peterson, Ben Shapiro and Yaron Brook.

24, how my daily habits (sitting, walking, ...) were the root cause of all my aches and how to adjust them to get rid of most aches. Still learning, but so far the results are incredible.

Interesting. How did you discover this?

41 - learning to trade options on the stock market.

"learning to trade" says almost nothing, as there are many different strategies that you could be learning. So what did you learn exactly? :-)

I'm not employing a specific strategy. A better wording would be discovering covered calls. I already own the shares so the downside risk is inherent. Betting against upside is great in these volatile markets, and given enough capital for the stock, I can buy 100 more if I get close to break-even price on the upside. For the last two weeks I sold calls for TQQQ.

I play this game airsoft (like paintball) and I like to go especially on beautiful days like today. It's so much cardio and you don't even notice it. Anyways, this Canadian company makes these really innovative reusable bang grenades and I finally learned how to toss them just right to clear out rooms. In movies the badass hero makes perfect throws without even thinking. But turns out in real life having your gun in…

The correct way is to have your team cover you and throw with your dominant hand.

29; the last thing I learned was the importance of sleep, which I've heard about before but never really internalised until now. One of the coolest parts of this that I learned is how in certain stages of sleep you get this stuff called "sleep spindles", the activity of which is associated with memories from your short term memory buffer in the hippocampus being relocated to your long term memory in the cortex. This sleep spindle activity can be measured in pulses in your brain during this stage of sleep, pulsing between the hippocampus and the coretex at a rate of 100-200ms. Upon waking you are left with longer term recall of what you had learned pre-sleep, plus your short term memory buffer in the hippocampus is now free to learn new stuff. Our brain is so exciting!
