Just to add to my previous post, here is an article about the benefits of drinking tea

Take time for tea
New research carried out by Unilever scientists could help us understand why taking time out for a cup of tea is beneficial and can make such a difference. They have established that a normal cup of tea typically delivers 22mg of theanine.
Stimulate more than your taste buds
The effects of 50mg theanine, the amount present in 2-3 cups of PG Tips tea, is known to stimulate alpha brain waves which are associated with being relaxed yet alert. Alpha activity is thought to be important for the ability to focus attention.
We explored this reltionship further in the context of a typical PG tips brwe - the new study indicates that the leaves found in our normal everyday cupy may improve ability to focus. The study found that people who drank two cups of PG Tips tea were not only faster but more accurate at performing tests that measured their ability to focus attention. The odds of a correct response on one test of attention were increased by 40%.
Whereas coffee offers a stimulant from caffeine, tea is the only drink that naturally contains both caffeine along with the less common effects of theanine. The level of caffeine in tea is also much lower overall than brewed coffee (approximately half in an average sized cup).
The PG Tips study
The study was carried out by scientists at Unilever on healthy volunteers who consumed two cups of PG tips tea, made with pyramid tea bags. The volunteers performed computerised tests that measured their ability to focus attention. This is the ability to ignore distracting information and is synonymous with concentration. In the laboratory, it is measured by presenting more than one piece of information at a time, but with instructions to process and respond to only one. After drinking PG Tips tea, there were significant improvements in both the speed and accuracy of their performance.
