Yes, like receding hairlines and pendulous earlobes, it seems your daily 3 o'clock caffeine craving can also be traced back to your genes, according to new research released this week.
As USA Today reports, scientists have identified two genes that decide whether you're a double-shot-of-espresso sort of gal or a "one-cup-gives-me-the-jitters" kind of guy. Essentially, depending on whether you carry a "high-consumption" variant or "low-consumption" variant of either gene determines just how fast or slow you metabolize caffeine, and thus, just how much java juice it takes to get your motor running in the morning.
