If you have carpal tunnel issues, I can highly recommend the RollerMouse RED. It’s not a trackball, but a unique rolling bar controller that I’ve been using for several years now with none of the RSS issues I used to have. Not the cheapest option for sure, but the least physically stressful input device I’ve ever used.
This is FFT-Based resynthesis, and a not very good-sounding implementation at that. It’s understandable this is the technique that would be chosen as that the format of the data used lends itself to averaging/blending. However, after the bombastic headlines, I am truly disappoint.
Actually it applies to everyone who consumes it, and the body has a limited ability to compensate for it.
This works for a period but eventually fades to the point where you take in caffeine just to reach the level of performance you had before you used it.
The quality of work is often different as well, in my case it's more of a pushing to get things done at any costs, without refinement or nuance.
BTW- If you google "caffiene brain blood flow" you'll find out that it reduces blood flow to the brain by 20%. That can't be good...
