I don't have to actually sit down to be able to decide what I use my computers for or what I do on them for most of the day. As a matter of fact, too much sitting is bad for health. Taking more frequent breaks is only one example of how that is possible to avoid, and taking more frequent and/or longer breaks also helps to gain better focus and attention so it also helps to reduce stress symptoms like eyestrain and bodily fatigue, headaches, neck/shoulder/back problems, etc.. What most people don't seem to know is that, after taking a break, the time that it takes for the average person to regain full focus of attention on workflow very often tends to be substantially longer than the time that it takes before the negative health effects that result from remaining in a seated position begin to kick in again.
That's why I usually lie down in front of my big TV, that I use as my main computer monitor with my K800 wireless keyboard on my lap, whereas some others swear by standing at a computer desk table that has a (motorized) adjustable height. Using a big TV also helps to reduce eyestrain for me due having a much longer distance between my eyes and the TV, and, although standing upright at a computer table doesn't exclude the option to use a bigger computer monitor/TV (as you don't necessarily have to put the bigger display device on this same table of course; you could always decide to put it at a farther distance on a separate table/wallmount), I still prefer to lie down, simply because it reduces more of my own stress symptoms. Opinions don't even come into play. Instead, it's just an easy determination like cause and effect. Similarly, productivity also depends heavily on health and on people's ability to focus on workflow for longer, while not having to waste valuable energy and time with a stubborn UI. That plus the fact that about 20% of the population are
HSPs.
Finally, I'll be the judge of what's the number of items I need/want to see in my Start menu and of how I want to keep them accessible and organized. I use Windows 11 because it allows me to use tweaks to accomplish exactly that, on top of lets me achieve all my workflow
all day and all of the night.
