I imagine that my question will make you smile and that there won't be many answers but I'll give it a try.
Have you ever tried to draw/design (whatever the CAD/CAD software) while walking on a treadmill (0-4 km/h above I think it becomes very difficult to be precise). ?
No never, I tried sitting while sleeping, that's possible! I also tried by walking on my hands and doing a handstand, now it's complicated not to lie to you! I imagine it's possible but already standing to draw I have a hard time walking! Yes, the accuracy of mouse clicks must be random, you don't have to have Parkinson's on top of that!
There is a solution: a carpet that is not motorized. Concretely the idea would be to design a treadmill on bearings, which only moves if you walk, which would allow you to stop when you need stability (and in SW it would not be a luxury :p). And as a bonus, it's zero consumption, it's ecological.
It is the user who would move the mat forward, not the other way around, promoting a more natural behavior of the muscles that work to get the body moving, instead of working to counter a workout undergone. In real life, we are the ones who move forward, not the road that moves
It's easier to stop drinking and go for a run or ride before, after or during the lunch break. Nothing but walking and carpeting in the same sentence...
The meal break serves as a social bond... In addition, we are not lucky enough to have a changing room with shower. So sport between noon and two is dead (and the rest of the time it's with the family). And for the treadmill... There are plenty of them in the gyms...
