Stimulants usually make you burn more energy, so they're fertile ground now that calories are cheap. Dietary energy has only been affordable for a couple of centuries, so there's not a lot of time to have evolved more wasteful bodies and minds.
Coffee may be good for your healthspan but addiction to caffeine is real and you lose the nootropic benefits if you hit it every day, as most coffee drinkers do. In fact, it's worse than this, because your brain performs worse before it gets its coffee, at which point a daily drinker will just arrive back to baseline performance. Not to mention the irritation, "don't talk to me before my coffee", etc. that other people have to deal with before you get your fix. Or the hit to your wallet whenever you purchase coffee from your local barista.
I want to be clear I'm not throwing shade on the other healthspan benefits of coffee that do come from daily drinking but pretending coffee is a free lunch is naive.
I love coffee, but noticed I get grumpy and feel a bit stiff in the joints if I drink more than one cup a day, and sometimes I alternate with tea. That's all I really need to determine what works for me. I highly recommend when conflicting media reports are everywhere to start evaluating your background like that to create calm (if you can do so of course) or simply to embrace your mortality and realize that pollution and other factors make everyone's future quite unpredictable regardless.
I found out that I am sometimes allergic to citric acid, which turns out is made from mold. If I have more than one citrus flavor drink I get sore joints. Theoretically the mold is filtered in the final product but I suspect this is not always done well. I just avoid it now but dang its in everything.
Coffee supposedly has trace mold on it could be a similar problem.
