For a lot of people...Coffee is life, and this new research (published in Consciousness and Cognition) says just LOOKING at a cup of coffee in the morning is enough to perk us up. The effect, which can even be sparked by just thinking of anything that reminds us of a latte or espresso, is more pronounced than with tea. I don't buy it. If you're a coffee drinker you know that the very first sip is what does it... not the thought of having it.
