I think a better preface would be "I was going to say a joke about the postal service… But it always has a poor delivery."
For those interested, the book Why We Sleep by Matthew Walker has very understandable details about sleep. He touches on the waste removal during NREM. He initially became interested in sleep by finding that Alzheimer’s was first predictably detected in changes in EEG sleep waves before symptoms of forgetfulness began.
Most comments seem to be focused on the logistics of applying and financial concerns. Those are important, but before that I would strongly suggest you evaluate your reasons for doing the program and understand your commitment. For one, interviews and applications will want to know this anyway, and two, these reasons can be tested when things get difficult.
A few insights: school has changed in the last few decades. Things are more lean and there is more expected from students. A big divide if you consider a PhD program is whether it is a researched based (eg R1) or teaching school. A research based school is more competitive and honestly feels like a business sometimes. How many papers can you crank out? Can you devote extra time to helping research professors so that you get better opportunities?
There is a changing (and unclear) landscape of software. Sources libraries and PDF organizers can be helpful. Most the students I know are using some form of AI to read or write papers, and they make edits and such. There is ongoing debate on the ethics, but people are using it regardless. If the precedent becomes writing papers at the efficiency of using AI to structure the papers, the level of expectations again rises.
Also be sure to have a support system in place. Things can get overwhelming and frustrating, and leaning on people when needed will be important.
Start with really pondering your reasons for doing the program and see if a program would fit those needs. And it would be a great idea to reach out to current students at least a couple of different schools to get their input on how the program is. There is only so much you can gain from reading the website. If it is really what you want to do, start looking at the requirements and email the program director or assistant to see if you’re missing anything.
That might have been me, I always ask for more visual options haha. The colors really make it more pleasant to use. Anecdotally, the performance seems better with transparencies off, using opaque colors. 
Thanks for the tip for testing the colors. And sharing the preview. I’ll try editing my post to have the previews included.
Also on a personal note, make sure you pace yourself and take breaks. There will always be more to improve and sometimes I think people feel that they need to push themselves. It can wait. Two of my favorite Lemmy apps kind of just stopped flat, and my hunch is that the developers got burnt out.
Wow, thank you for all of the hard work. The themes had me so excited (especially Cremé) but then I saw a… theme maker option?? I literally spent an hour fiddling with a theme and found a combination that I like.
Here are the theme files, if anyone wants to try them. Also it’s the first time sharing files via Proton Drive, so let me know if it works:

Eventually it would be great to have the labels possibly be easier to figure out what it is changing.
Huh, I got the same result when using the Lemmy Explorer section and searching for an instance with "Exclude NSFW" selected. If I searched by community instead of instance, it worked and included the instances you mentioned. Weirdly it actually included at least one community that was NSFW with "Exclude NSFW" selected.
