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.
