Could always get back at that asshat by donating your Tesla to PBS or NPR (assuming of course you could afford it).

But the social media research I did says Vitamin A is the natural way to build up immunity! /s

Snake oil sales persons everywhere. Supplements should have been regulated by the FDA from its inception.

I suggest you enjoy your placebo effects and take a physiology course. (You can verify that this is the placebo effect by studying and doing research, but I won’t link how to do that for you, I know that’s unkind of me to do)

Go peddle your snake oil elsewhere.

OP, go see a medical doctor who knows more about human physiology than some snake oil sells person on the internet.

It’s possible to still track speed using a video feed instead. You just have to know the distance between two static points within the videos frame. Time naught = passes first static point, time final = passes second static point.

Velocity = distance / time

Although I’m not sure how or if this would impact the battery life of the device.
