Caffeinated water

Non-caffeine drinks, such as Decaf, are popular from the viewpoint of health and religion in USA and Europe. It is just different situation from Japan, where heavily caffeinated drinks are popular for students and businessman to prevent from getting sleepy. When I was a member of committee to manage a 10th ICRS (International Coral Reef Symposium) held in Okinawa last year, I felt kind of cultural difference for other member’s opinion that we should prepare Decaf. But I was amazed that such a healthy food was actually so popular. I think that scientists’ preference for food and evaluation for President are little bit different from average opinions. A couple of days before, Erin asked me why I was drinking caffeinated water. I had not found it was accidentally caffeinated one, though I did not mind whether it include caffeine or not.
