Frequently Asked Questions

Is this fearmongering about coffee?
Nie — fact-based math. Coffee itself is fine (some health benefits per Lancet 2017 meta-analysis). The point is: a daily €5 latte is €1,825/year — over 30-year career = €54,750 spent OR €184,000 if invested at 7%. Most people don't calculate this. Awareness ≠ banning coffee.
But coffee = quality of life?
Absolutely. The point isn't "stop drinking coffee" — it's "make conscious tradeoffs". Maybe €184K invested matters less to you than daily ritual. That's valid. Maybe brewing at home (€0.30/cup) for €0.30 × 365 = €110/year is enough. The choice is yours; the data is the data.
Does this apply to other small purchases?
Yes — it's called the "Latte Factor" (David Bach). Same math for: daily €4 sandwich, €3 protein bar, €5 streaming-snack. Any €3-5 daily habit = €25K-50K career-cost. The aggregate of small habits often exceeds big purchases.
