Really? As if the first clickbait was not enough?
I didn’t see a VPN ad in the 2nd one (or maybe I wasn’t paying enough attention), which is unusual because these guys have been putting VPN ads in their videos for years. And before that, they put in plugs for a brand of motorcycle.
If I remember right, the South African guy is a motorcycle mechanic and the American guy is an engineer of some sort—they aren’t medical people. I find their videos interesting as they lived in China for years and have an insider’s perspective on what has been going on in China (corruption, the brutal communist government, lack of sanitation, etc).
