Margot is not exactly working up a sweat when the camera finds her at home on her exercise bike. But why would she need to work up a sweat? She drinks Tab and this stuff is sugar-free.
This commercial demonstrates how, while time marches on, the trends in food consumption are about the same. Only the ingredients have changed. In the 1980s, everyone was concerned about calcium and they were shoving it in just about everywhere they could stick it, including Tab. I have not seen calcium in a soda since the 1980s, so I guess we really didn’t need all that calcium. Keep that in mind when they are selling you shampoo with vitamin c or caffeine in it.
