An actor's popularity is dependent on if they have a major role in popular movies, a large social media presence, or things like that. Many people don't exactly care about quality in movies, or the actors ability to act.
There are some great actors we probably never heard of, because they are cast in minor roles, or in movies barely anyone knows about.
Depends. Lots of shit doctors out there who don't care avout their patient. I've seen guys go to a doctor with a problem, only to be barely checked, if at all, and sent home with an unhelpful prescription or advice.
Plus gender-epecific conditions are poorly taught in med school, or to the wider public in general. Most members of the opposite sex rarely know about conditions affecting the other, or even their own. As a guy, I've learned about Endomitriosis because of youtube. But also I've learned that men have much worse symptoms with viruses than women, from a TV show.
Thankfully there are many doctors who take their job very seriously, but it seems they are hard to come by, especially in the US.
