I'm in my late 30s. So maybe not so far away from the age of lack of energy :P
I like JetBrains a lot. Things work seemlessly and easily integrate with external tools that make up the whole experience. But from 2012, I tried to rely as much on shortcuts as possible, for one simple reason, the mouse.
There is no problem with using the mouse. But everytime I have to use while focusing and coding, I find that that small gesture to move my hand from the keyboard to the mouse a bit flow breaking.
I have to move to the mouse, do a thing or two, then find my way back to the J key notch.
I like what NeoVim and emacs bring with regards to the reliance on the mouse. They allow for maintaining the same posture most of the time and focus only on typing.
I dislike how brutal they are at learning how to use them to full potential, and that making them into IDEs takes ages of IDE building rather than project coding.
I like Helix. Which takes a lot of inspiration from Vim/NeoVim/Emacs. But require no configuration to get you going right away.
The documentation is easy to read, as of now there is no plugin system but there is a builtin integration with a lot of LSP servers for most of the popular languages by default.
Keys and navigation is easy, it even shows a helper popup to show you which key to use next.
My suggestion is, if you ever want to start a new silly project, and you're feeling free to take it slow for 2 days. Try using Helix on said project.
PS: Helix isn't fully complete by any means, but it really is capable of doing everything you want in many projects without being a hindrence if you can adapt to the lack of some built-in features like git and file tree. Its annoying but I am less upset about it and use alternatives
