Total click bait. Life is just not that complicated unless you make it out to be. I don't know if he went on to say something intelligent, his strawman man farce up front suggested otherwise so I stopped.
Sorry, where are the regulations on that? Of course wide mugs helps them cool off better if thats your goal, but if you want it to stay warm longer, tall is actually better.

For example, a lot of people drink coffee while driving, but almost no one would have a wide mug like that. They have something tall and with a lid. Common sense.
I have zero issues drinking while wearing mine. Coffee. I meant coffee.
