I often see the large size soda cup being bought by the younger generation. It makes me wonder how they can finish that much soda in one sitting. I am also a soda drinker and it is Coke for me. But the medium size cup is more than enough for me. Anyway, I hope that those kids who drink so much soda will not have diabetes in the near future. Their body may get used to the sugar and there might be a health issue when they get a medical checkup.
