Instruction:
Why would someone want to drink sparkling water instead of flat?

Response:
That's a great question! There are a lot of people who have grown up drinking beverages that taste good, but aren't necessarily good for their health, such as soda. As we age, we often start to consider our health more seriously. Sparkling water, like soda, has bubbles and gives a similar sensation, but has fewer calories and sugar, and therefore better for your health.
