Between the trackpad and the nipple, definitely the nipple.
It took so long for me to get half as good at the trackpad (after increasing its speed in the settings) as the nipple (with which I even managed to play Quake III (Old ThinkPad)). And this is saying as someone who can't use the gamepads.
Of course mouse is best though. Never tried a vertical for long enough and fixed my carpal tunnel onset by just being more physically active.
Another way is to put magnets under your normal mouse and set it on a slanted metal plate.
Now I am kinda interested in trying it out. Need to find some powerful magnets nearby.
An eye tracker sounds nice, but there are times when I want my cursor to be in another place while I am looking somewhere else.
On the other hand, if I could pair it with my multi device keyboard's device selector, it would be great.

Pretty sure musicians would be using that instead.
Replace "machines" with "organisms".
Another one is air quality.
If you are breathing in too many undesirable aerosols when you sleep, you are not getting better, but worse.
If you didn't have to mine them out of something and just picked them off the ground, they are pickerals (= rocks).
Get on with the reflogging.
Perhaps the LinkedIn user should have considered learning "programming" instead of just C++
