                                According to research, the human body's ability to process caffeine can vary up to 12-fold, suggesting a wide spectrum of individual tolerance. This significant variation explains why some people can consume a large espresso before bed without issue, while others get jittery from a single cup of tea. So, can some people handle more caffeine than others? The answer is a definitive yes, and it lies primarily in our genes and lifestyle.
