Although I'm sure there's variations in heart rate that aren't healthy.
I used to think visual character design was the hardest thing ever. To just come up with something out of nowhere. that being creative like that was a very difficult thing. What I didn't usually see or look at is all the designs those people have seen and taken inspiration from before.
I think that's also why some ideas can be "ahead of their time". Someone made a connection between some concepts that many people haven't yet, and will think is too farfetched. Still, over time people can come to see value in that idea that was dismissed earlier.
Just to reiterate my main point, I think it's easy to look at what other people do and think "Wow, how original!", without ever seeing their inspiration for something. Even though they might just feel like they replicated some patterns.
