If I needed something to get me through a whole day of work, what would be best to drink - coffee or tea?

Coffee is a great drink, and it’s also helpful when doing a lot of work, as the caffeine helps keep you alert and focused.  But depending on what work you’re doing, you might want something a bit more calming to drink than coffee.  Tea has the same amount of caffeine as coffee, but it’s sweeter, which can help calm you and provide a more consistent level of energy throughout the day.
