Mostly, yes. Heart rate variability ties into the sympathetic and parasympathetic nervous systems. When both are in balance, heart rate will fluctuate with the alternating activation of those nervous systems.

Although I'm sure there's variations in heart rate that aren't healthy.

Who's out here speculating on roads?

ASTM, sovereign wealth funds, etc. Toll roads can be a pretty good investment.

Nobody, and it should be the damn same with housing.

What I find funny is that the description of your version of "creativity" is my general definition of creativity. Has anyone ever done anything completely original and unheard of before? I think to be creative at something is to have a large mental library of concepts within a certain space, and to be able to mix and match those concepts. Much like ripping ideas apart and slapping them back together as you say.

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.

To be out for blood is to seek revenge. I read "Give up blood sport" as a caution against doing so.
