So have a Diet Coke. Because you can! It's so much easier than doing something healthy, like training for a marathon. Life is short, might as well trash your body. You're going to die anyway.
And this is coming from someone who drinks way more diet soft drinks than I should. But I don't try to justify them. I know they're not healthy and I should cut down on them. But this approach...I just don't get it. On the other hand, maybe I should give them props for almost being honest, but I just don't understand how advertising professionals thought this was a good idea. And judging from the comments on YouTube, I'm not alone.
