> Stay up late because I’m wired on caffeine and dopamine from scrolling. I wish people didn't overuse certain terms. Dopamine has a half life of 2 minutes in the body. It can't possibly keep you up at night. It's just the caffeine, which in turn has a half-life of several hours. Also below a certain level it's eliminated approximately exponentially, so there's a long tail of residual caffeine.
> Dopamine has a half life of 2 minutes in the body. May be true. But doing "rewarding" work encourages your body to emit more dopamine. Some people call it "the flow", others "hyperfocus", but it is a constant stream of dopamine that keeps you doing what you currently do. And you can interfere with the emittance and absorbtion by using caffeine.
I have never understood why people feel the need to use terms like "dopamine" in very pop culture and highly unscientific way, instead of just describing the state that they are talking about.
