No time to watch right now, but I'll be sure to watch it before I grind anything else.
Kinda had the feeling I've been playing with fire the last few years. Need to get a full face/throat shield.

This is why I always wear eye protection and dont stand in the path but to the side of what Im grinding. I also DONT remove the guards, ever..
Video won't load for me,
But a few years back there was a bloke at work using a cutoff wheel on a 9" grinder, and it kicked back and cut him from the top off his left eye to the right of his chin, with a guard and face shield.
Then there was the time someone left a set of oxy-acetylene bottles on a trawl boat, turns out they were leaking and he out up a ciggarette, the rest covers itself.

Can't watch the vid without logging in so I'll share my angle grinding experience with a pic. I was building a frame to body drop my yukon and knelt down beside the new rails to grind some welds when the 7" grinder kicked back into my kneecap cutting though my dickies and leg like nothing. At least I had on eye protection.
This has come up a few times. I use a Uvex Bionic face shield which seems popular amongst GJ members. I'm quite happy with mine.My guards went back on many years ago, still need to get a decent full face shield.
yup I dunnit too
this spring I was using a 4" flap wheel to sharpen a mower blade. Though " heck I'm not putting the guard on - it will only take a minute". Holding the blade down with one hand and the grinder in the other, slipped, buzzed the skin open in a flash.
But, about a month ago, did it again. Started the project reminding myself what happened the first time and how not to do it again. Clamped the blade down, was grinding along, hand slipped and slide right up to the disk and - buzzed my hand good.
The guard is back on now.
just to be clear, I remove the blade from the mower also.I always take the blade off the mower and sharpen on a bench grinder....
