You will have better memory. Science proves it.
The investigators found that older adults who drank a 12-ounce cup of regular coffee before taking a memory test performed better than their peers who drank decaffeinated coffee. Not only did caffeine drinkers have higher scores on the test, which was given in the morning and afternoon, but they did not show any decline in memory throughout the day.
Test scores declined significantly between morning and afternoon in people who were regular coffee-drinkers but consumed decaffeinated coffee for a day.
